Feature scans:
- Proton/Linux: score 20; verdict: No Linux/Proton evidence; no friction reported; summary: The provided reviews contain no Linux, Proton, SteamOS, Wine, or Steam Deck compatibility discussion. Feedback is exclusively about gameplay, difficulty, characters, and Discord lore. No Linux-specific launch, performance, anti-cheat, or workaround issues are reported, so no Proton/Linux friction can be identified from this dataset.

- Hardware Profile: No data
Feature extractions:
- Community Price: No data
- Playtime Metrics:
  - Game completion: N/A
  - Story completion: N/A
  - Session length: 1.0h
  - Endgame: N/A
  - Reasoning: The only supported metric is sessionLength: one reviewer estimates negative players spent about an hour and did one or two runs, and another reports being an hour in, suggesting a typical session of roughly 1 hour. The 3-hour comment describes incomplete story progress rather than completion, and the comment about beating the game gives no hour count, so gameCompletion and storyCompletion remain null. Mentions of replay value provide no endgame duration, so endgame is also null.
- Time-to-fun:
  - Summary: The game's fun is most explicitly gated by understanding its unexplained systems: once those systems click, players describe it as incredibly fun, though some report immediate fun while others bounce off clunky combat and co-op dependence.

  - Time to anchor: N/A
  - Friction: Game does not explain most of its systems; Combat feels clunky and enemy hitboxes feel unfair or inconsistent; Co-op is hard to access without a friend who also buys the game; Game appears balanced around co-op even with mob HP and upgrade-cost scaling
  - Unlock drivers: Understanding the game's systems until they click; Playing co-op, which adds depth and replay value
  - Conditions: Enjoyment begins once the unexplained systems click; Co-op availability depends on having a friend who buys the game; Co-op play adds depth and replay value; Game can also be played very well solo; Balance is tuned around co-op even with mob HP and upgrade-cost scaling; Clunky combat and hitbox issues can prevent enjoyment for some players

Common complaints:
- Game Needs More Polish (weight 0.74): Many reviewers agree the game feels unfinished, with rough edges and a general lack of polish. It requires more development time before it can be considered a complete release.
- Visuals and Animations Feel Unfinished (weight 0.71): The game's 3D assets, VFX, and animations are described as half-baked, rough, and placeholder-like. Specific effects, such as the flaming sword, look like poorly animated neon glowsticks.
- Progression and Upgrades Feel Unsatisfying (weight 0.57): Many upgrades and level-up rewards feel meaningless, with weak stat increases and a lack of variety. Leveling up takes too long, making progression feel like a grind.
- Combat Lacks Weight and Impact (weight 0.54): Combat is described as mushy, clunky, and haphazard, with hits lacking a sense of impact. Attack animations and hit feedback feel weak and unsatisfying.
- Clunky Controls and Movement (weight 0.53): Players report that controls are clunky and poorly responsive, with delayed jumps and little air control. Movement overall feels janky and uncontrollable.
- Inconsistent and Unresponsive Dodging (weight 0.47): The dodge mechanic is widely criticized for being extremely inconsistent, often failing to register or behaving unexpectedly. Reviewers note that the dash-dodge is uniquely bad and makes it hard to tell if it's working.
- Map Design Is Barren and Frustrating (weight 0.41): Maps are too barren for their size, with catapults acting as a band-aid fix for traversal. Some areas have bottomless pits with no obvious way back, and a jumping puzzle in heaven is nauseating.
- Hitboxes Feel Unfair and Inconsistent (weight 0.39): Hitboxes frequently do not match visual indicators, leading to frustration. Enemy attack hitboxes are often perceived as unfair, sometimes phasing through the player.
- Enemies Are Too Tanky and Numerous (weight 0.38): Common enemies are overly tanky from the start, making even basic foes take too long to defeat. Later levels throw tens of enemies at once, overwhelming the player with AOEs and bullet patterns.
- Bugs and Technical Issues (weight 0.36): Numerous malignant bugs can ruin runs, such as falling into sky city areas and getting stuck underground. Controller inputs are not configured properly out of the box, requiring custom mapping.
- Difficulty from Lack of Control (weight 0.36): Difficulty often stems from a lack of control over the character rather than fair challenge. Movement is uncontrollable, and players feel they get hit without deserving it.
- Time System and Map Design Clash (weight 0.35): The time system seems added without regard for the rest of the game, clashing with map design. Losing instantly at 100% sin is a problem, and the timer feels too short to upgrade meaningfully.
- Screen Obscuring Effects and Fog (weight 0.3): Effects like smoke, fog, and visual clutter often cover the screen, making it impossible to see enemy attacks or dodge. The fog world event is particularly problematic, ranging from a nuisance to a run-ender.
- Lack of Build Variety and Meta (weight 0.29): The game lacks viable build variety, with an obvious meta for relics and abilities that limits creative build crafting. The roguelike hook is disappointing due to this lack of diversity.
- Character Balance Issues (weight 0.29): The katana character is vastly overpowered compared to the initial magical girl, who performs poorly. The last unlockable character's cloning ability also seems like a cheat.
- Poor Onboarding and Guidance (weight 0.29): The game fails to explain most systems, leaving players confused about what to do. Guidance is weak, making it hard to find objectives like the second flower seal.
- Combat Lacks Clear Identity (weight 0.28): The combat system doesn't know if it wants to be a hack-and-slash or a slow, methodical beat 'em up. Regular enemies lack identity, and getting hit rarely feels deserved.
- Repetitive Gameplay and Stale Loop (weight 0.28): The core gameplay loop is not satisfying on its own, leading to feelings of staleness. Repetitive maps and biomes become tiresome over time.
- Multiplayer and Co-op Issues (weight 0.27): Finding multiplayer matches is difficult, especially outside North America due to low player counts. The roguelike mode feels designed for co-op, but the lobby system fails to find rooms.
- Pricing and Value Concerns (weight 0.26): Some players feel the game is expensive for what it offers. The Steam version also does not include the Fernet skin, adding to value complaints.

- Build variety and upgrades (weight 0.51): Players can create different builds using relics, abilities, and upgrades. There are permanent enhancements and skill purchases at a base.
- Soul-based leveling system (weight 0.46): The game features a leveling system that uses a soul currency with increasing costs. This system is used to upgrade character stats.
- Boss and mob combat (weight 0.46): Players fight against bosses and groups of enemies. Boss mechanics are a notable part of the game, including a final boss that is a god.
- Multiple difficulty levels (weight 0.45): The game offers multiple difficulty settings, with the maximum difficulty being recommended for experienced players. Weapon choice also affects difficulty.
- Dodge and lock-on mechanics (weight 0.43): Combat features dodge mechanics that also function as dashes. A lock-on system and i-framing moves are present.
- Combat polish issues (weight 0.36): Some players report that combat feels unfinished and dodging is inconsistent. Enemies can take too long to kill, and screen clutter affects visibility.
- 2D animation and visual novel elements (weight 0.35): The game features 2D animations and visual novel-style elements. It also includes story-driven segments and character conversations.
- Time-limited resource gathering (weight 0.28): The game includes time-limited resource gathering and stage timers. Reaching the time limit spawns a difficult boss enemy.

- Ability combination system (weight 0.12): Players can combine abilities to create powerful effects. This synergizes with the build variety and upgrade systems.
- Sin meter and instant loss (weight 0.11): A sin meter causes a run to be lost instantly at 100% sin. This adds a unique risk-reward element to gameplay.

Performance notes:
- High frame rate on max (weight 0.13): A reviewer reports the game runs at up to 120fps constantly on maximum settings. This indicates strong optimization for high-end hardware.
