Info about ON&OFF:

Official game description:
A turn-based deckbuilding roguelike where you place magical cards on a grid and connect signals.
**Reactivate Used Cards**
-------------------------
In a typical deckbuilder, cards disappear after being used once. This game is different — cards remain on the board, switching between ON and OFF states, and activate their effects each time they turn back ON from OFF.
If you reactivate the same defense card twice, its defense is applied twice. If you reactivate the same attack card five times, it becomes a five-hit attack.
The true power of your deck is not just how many cards you have, but where you place them and how you turn them back ON.
**Send Signals and Connect Chains**
-----------------------------------
When a card turns ON from OFF, it activates its effect and sends signals to nearby cards in the direction of its arrows. A card that receives a signal switches between ON and OFF. Among those cards, only cards that turn ON from OFF activate their effects again and continue sending the next signal.
Turning on just one card in front of you is not enough. Place your cards so that the signal flows from one card to the next, then to the next again, expanding a single activation into a powerful chain. You can create short, reliable chains, or design massive flows that cross the entire board.
**Placement Is the True Power of Your Deck**
--------------------------------------------
Having powerful cards is not enough.
What matters is reusing the effects you need from the cards you have already placed. Reactivate attack cards to stack up damage, trigger defense cards again to block incoming attacks, or prepare the board for your next chain.
**Complete Your Own Way of Activating Cards**
---------------------------------------------
Gain new cards as you fight, and build a deck with cards that work well together.
You can move the board in many different ways: a deck that repeatedly awakens one key card, a chain deck that activates many cards at once, or a deck that builds up cost and unleashes it all at once. Through choices that change with every run, complete your own chain structure.
**Key Features**
----------------
*   **Reusable Cards** — Cards do not disappear after being used once. They remain on the board, and whenever a signal turns them back ON from OFF, they activate the same effect again.
*   **Signal Chain Design** — The path of a signal changes depending on each card’s position and direction. With a single placement, complete a massive chain that crosses the entire board.
*   **Effects That Activate When Turned ON** — When a card switches from OFF to ON, it activates its unique effect, such as attack, defense, or draw. Which cards you turn back ON, and how many times you do it, determines the outcome of battle.
*   **Reusing the Effects You Need** — What matters is not creating new effects, but bringing out the effects you need from cards you have already placed. Reactivate attack cards to stack up damage, or trigger defense cards again to block incoming attacks.
*   **Build Your Own Chain Deck** — Gain new cards through battles and build your deck. Move the board in many different ways, such as a deck that repeatedly activates a key card, a chain deck that triggers many cards at once, or a board-building deck that prepares a major activation for the next turn.

Feature scans:
- Proton/Linux: score 30; verdict: Minor Steam Deck Friction with Limited Evidence; summary: The feedback contains no explicit desktop Linux or Proton troubleshooting details. Two Steam Deck-related comments suggest the title is not officially confirmed as Verified or Playable and is somewhat rough to play on Deck, but they do not identify launch failures, anti-cheat/DRM blockers, or necessary Proton tweaks. The evidence is too sparse to assess desktop Linux stability, so the audit reflects minor Steam Deck-related friction rather than severe Proton incompatibility.
- Steam Deck: score 45; verdict: Tinkering Required; summary: Steam Deck evidence is limited but consistent: compatibility is described as unverified, and one user reports that the game is rough to play on Deck despite strong mechanics. Reviews note modest hardware demands, which is favorable, but there are no reports of crashes, anti-cheat failures, external launchers, unreadable UI, or confirmed Proton toggles. The result is a playable-but-uncertain Deck experience that warrants caution or tinkering rather than a broken classification.

- Hardware Profile: No data
Feature extractions:
- Community Price: No data
- Playtime Metrics:
  - Game completion: 2.5h
  - Story completion: N/A
  - Session length: 1.0h
  - Endgame: N/A
  - Reasoning: The reviews repeatedly describe a short free experience lasting a few hours, with one explicit 2-3 hour range, so gameCompletion is estimated at about 2.5 hours. A Japanese review states that one full run to the end took about an hour, which supports a sessionLength of roughly 1 hour for a complete run. The 10-hour figure is tied to 100% completion rather than a clearly isolated post-completion endgame phase, and there is no separate story completion evidence, so storyCompletion and endgame are left null.
- Time-to-fun:
  - Summary: Players tend to start enjoying ON&OFF after pushing past a weak opening/tutorial and getting used to the chain-building logic, with one report citing about 10 minutes. Some call it fun or addictive immediately, but enjoyment is often conditional on the chain mechanics clicking.
  - Stance: Clicks after
  - Anchor: After about 10 minutes of play, once the player gets used to the weak opening and tutorial
  - Time to anchor: 0h 10m
  - Friction: Weak opening and tutorial; Learning curve; Cannot immediately see the needed chain; Getting stuck when the chain is not apparent
  - Unlock drivers: Playing for about 10 minutes and getting used to the game; Everything clicking into place; Seeing the chain reaction you need
  - Conditions: After about 10 minutes of play; Once the player adjusts to the opening and tutorial; When the needed chain is visible; When the mechanics click; Patience with the learning curve

- Enemy intention telegraphing adds depth (weight 0.08): Enemy intention telegraphing gives combat a calculated quality, reducing reliance on lucky draws and adding strategic depth.

Common complaints:
- Infinite loops are too easy (weight 0.97): Multiple reviewers report that infinite loops can be achieved early and trivialize the game, often requiring only a few cards. This undermines the challenge and depth of deck-building.
- Limited content and replay value (weight 0.4): The game only has 3 acts and lacks content volume, variety, and depth. Replay value is low because the strategic breadth is small.
- Game overall too easy (weight 0.39): Many players find the game easy, especially once core strategies are understood. Even Hell difficulty can be simple due to poor balance.
- Limited card variety (weight 0.38): Reviewers note a lack of card diversity and interesting card designs, leading to repetitive runs and limited strategic options.
- Game feels unpolished (weight 0.38): The game is described as rough, prototype-like, and lacking polish. Some mention missing disclosure of AI assets.
- ON/OFF mechanic complex (weight 0.32): The ON/OFF mechanic is hard to grasp initially, and efficiently arranging cards requires practice, which may deter newcomers.
- Overpowered specific cards (weight 0.32): Certain cards like 'Book of ㅇㅇ' and Predation legendary are considered too strong, especially when they enable instant kills or easy infinite loops.
- Hell mode unbalanced (weight 0.31): Hell mode is extremely difficult with high damage, armor clearing, and low rewards. Strong cards require too much energy, making them hard to use.
- Early enemies deal high damage (weight 0.27): Early enemies deal 25-28 damage, which is frustrating and forces healing, preventing upgrades. On Hell mode first turn damage can be 68 with only 80 max HP.
- Arrows dominate card usage (weight 0.26): Arrow cards become the most important despite many card varieties, making attack and defense cards effectively negative. Attack-related cards are not needed for infinite loops.
- Poor visual and audio presentation (weight 0.24): Graphics and soundtrack are average indie fare, with visual monotony and retro music that can become tiring.
- Loop building is difficult (weight 0.22): Building infinite combos or 2-3 combos requires too much effort, and storing only 3 cards per turn makes loop construction hard and expensive.
- Freezing issues with logs and compendium (weight 0.21): Enabling log collection or opening the card compendium causes the game to freeze. Reinstalling does not fix the issue.
- Balance issues with shop and upgrades (weight 0.2): Shop card upgrades and healing are not equivalent in value, and card removal costs too much. The choice between resting and upgrading feels badly balanced.
- Weak story and tutorial (weight 0.19): The story is considered lame, and the beginning and tutorial are somewhat bad, with early rounds feeling like chaotic trial and error.
- Shield-core strategy too strong (weight 0.15): A shield-core strategy with draw filtering and mana replenishment makes the game too easy, easily producing over 100 shield and trivializing combat.
- UI requires extra clicks (weight 0.13): Dialogue and description windows require pressing the yellow > button every time, and main menu functions cannot be used with a single click.
- Mid-game damage too high (weight 0.13): From mid-game, turn 1 damage of 20 or 30 often cannot be fully blocked, leading to low HP before boss fights and frequent losses.
- Boss resets break combos (weight 0.13): The boss always resets once, breaking combos and making it easy to die, which feels unfair.

Gameplay feedback:
- Infinite combo and loop mechanics (weight 0.85): The game heavily features infinite loops, chains, and stacking combos as a central mechanic, often created by combining multi-card toggle cards. Players build chains to win through infinite combo mechanics.
- Roguelike deckbuilder core (weight 0.82): Multiple clusters describe the game as a roguelike deckbuilder or card game with roguelike elements, often with a unique style and turn-based structure. It follows a Slay the Spire-like progression format.
- Arrow-based signal system (weight 0.48): Cards have arrow directions and send signals along arrows to other cards, changing neighboring card states. Arrows can be charged and toggled on or off in specific directions.
- ON/OFF toggle card states (weight 0.43): Cards alternate between ON and OFF states, and toggling them can trigger effects, chain reactions, and signals. This binary state system is a core mechanic of the game.
- Campfire arrow reinforcement (weight 0.25): Campfires or rest sites allow players to add arrows to cards and reinforce turn cards.
- Hell difficulty mode (weight 0.21): The game includes a Hell difficulty option, providing an extra challenge for players.
- Card grid placement (weight 0.16): The player places node cards on a grid, which is central to the gameplay structure.
- Combo-based card gameplay (weight 0.16): The game is a combo-based card game where players experiment with cards to build chains and combos.

Emotions:
- Satisfaction (weight 0.16): Players derive satisfaction from building and executing infinite loops and chain reactions, often through creative use of the on/off toggle mechanics. The process of setting up signal chains, witnessing carefully prepared combos devastate enemies, and the rhythmic hit feel with satisfying sound effects contribute to this emotion.
- Disappointment (weight 0.13): Disappointment stems from the game's low difficulty and poor balance, where infinite loops trivialize encounters and lack counter-gimmicks. Players cite limited replay value, minimal card variety, and a lack of polish that makes the game feel repetitive and underdeveloped.
- Frustration (weight 0.09): Frustration arises from harsh early-game damage, especially in Hell mode where enemies deal massive first-turn damage that is hard to block. Technical issues like game freezes when enabling log collection or viewing the card compendium, along with a high entry barrier and limited resources, further aggravate players.
- Fun (weight 0.06): Fun is experienced when players engage with the combo and infinite loop mechanics, enjoying the process of building decks and exploiting breaking mechanics. The game's requirement for strategic thinking and the satisfaction of making infinite chains contribute to an enjoyable experience.
- Interest (weight 0.05): Interest is sparked by the interaction between ON and OFF states and directional signals that produce chain reactions. The creative card on/off state, deck-building loop, and the potential to expand playstyles in various ways keep players intrigued.
- Enjoyment (weight 0.05): Enjoyment comes from discovering combos, experimenting with cards to create infinite loops, and the satisfying combination of planned chains with sound effects. The roguelike combination and the ability to create infinite chains by toggling the grid are particularly enjoyable.
- Amusement (weight 0.05): Amusement is derived from the game's creative systems, such as breaking the game with specific loop strategies and the mix of Slay the Spire and puzzle gameplay. The generous cost system and making loops with mana generation add to the humor and fun.
- Dissatisfaction (weight 0.04): Dissatisfaction arises from the ease of reaching infinite loops, which renders attack cards useless and forces repetitive strategies like adding arrows at campfires and deleting cards at shops. The lack of content and enemy variety, along with unbalanced shop values, limits motivation for varied challenges.
- Excitement (weight 0.04): Excitement is generated by figuring out infinite combos, activating all cards at once, and the dopamine rush from infinite chains. The anticipation of discovering loops and satisfying burst moments from combos heighten the thrill.
- Enthusiasm (weight 0.03): Enthusiasm is driven by the game's cool implementation, solid gameplay, and unique core mechanic. Players are eager to play more due to the game's premise and its potential, finding it fun and true to its essence.

- Delight (weight 0.02): Delight is felt from the neat fusion of mechanics and balanced infinite loops, as well as watching chains connect and cards react one after another. The game's interesting idea and cute characters also bring delight.
- Love (weight 0.02): Love is expressed for the chaining circuit mechanic, unique and fun game mechanics, and the loop-making mechanic along with the music. These elements resonate strongly with players.
- Confusion (weight 0.02): Confusion occurs when all cards remain on after enemies die and when players do not understand how infinite chains work. These moments create uncertainty about the game's mechanics.
- Appreciation (weight 0.02): Appreciation is felt for the depth that grows naturally from the central activation system rather than unrelated mechanics. Players admire the beautiful mechanics and how they integrate seamlessly.
- Surprise (weight 0.02): Surprise comes from the game being free and from the higher difficulty than its casual appearance suggests. These aspects exceed players' initial expectations.
- Confidence (weight 0.01): Confidence develops as players master the game, reducing difficulty to only mistake tolerance. Mastery over the mechanics empowers players to handle challenges with assurance.
- Fondness (weight 0.01): Fondness is directed at the cat in the shop, with players petting it every visit. This small interactive detail endears the game to them.
- Annoyance (weight 0.01): Annoyance is caused by having to press the yellow > button for every dialogue or description window. This repetitive interaction becomes tedious.
- Addiction (weight 0.01): Addiction is fueled by the 'one more run' feeling and big chain reactions. The compelling loop of runs and satisfying combos keeps players coming back.}
