Why players say this

Steam review verdict

Fun Portal-like puzzle game with great quality, but too short, too simple, and requires restart on mistakes.

What players like

Strong Portal influence appreciated: Many players enjoy the Portal-like feel, including gameplay, narration, and humor. This comparison is often positive, indicating the game successfully builds on Portal's formula.

Game is fun and enjoyable: Multiple players found the game genuinely fun and enjoyable over time. This positive sentiment appears frequently across reviews.

Excellent puzzle game quality: Reviews highlight it as a great puzzle game with well-balanced difficulty levels, appealing to puzzle enthusiasts. The game offers a satisfying challenge without being frustrating.

Puzzles are interesting and complex: Players appreciate the variety in puzzle difficulty, with some easy and some more challenging. The puzzles are generally described as interesting and enjoyable.

Concept is interesting and brilliant: The game's core idea is frequently praised as interesting, wonderful, or even brilliant. This suggests the concept resonates well with players.

Common complaints

Restart level after mistakes: Players frequently complain that a single mistake forces a full level restart due to lack of checkpoints or undo functionality. This occurs with both general gameplay and painting mechanics, breaking flow and causing frustration.

Puzzles too simple: Puzzles are frequently criticized as primitive, childishly simple, or too easy, causing boredom. Even when the game becomes more complex, it often remains unchallenging.

Softlock issues cause restarts: Almost every level has potential softlocks, where a small error leaves the player stuck and forces a restart. The lack of protection from softlocks amplifies the restart frustration.

Game is too short: The game lasts under four hours with very few levels, making it feel incomplete or barely a full experience. Players expected more content for the price.

Overly similar to Portal: The game tries hard to imitate Portal with a different gun, but fails, especially in the announcer's reduced commentary. The white tiles and gun mechanics are too reminiscent of Portal.

Gameplay and performance

Portal-inspired puzzle game: The game is consistently described as a first-person puzzle game strongly inspired by Portal, with test-chamber-style levels and a similar aesthetic. Several reviews note that some elements appear copied from Portal 2.

Color-based puzzle mechanics: The core gameplay revolves around using a paint gun to shoot blue, yellow, and red paint onto walls, floors, and droids. The primary mechanic is solving puzzles through color manipulation rather than combat.

Droids attracted to matching colors: Worker droids are floating spheres that get attracted to walls or surfaces painted with the same color. Players use this attraction mechanic to move droids onto switches or through obstacles.

Full color theme integration: The game revolves around the three primary colors and their combinations, with painting objects as the main puzzle-solving action. The color theme is deeply integrated into the visual design and level layouts.

Simple mechanic, deep application: The game introduces a straightforward painting mechanic but applies it in creative ways, such as directing drones and opening doors. The simplicity of the core loop contrasts with the variety of puzzle solutions.

Performance issues on older systems: Several reviews mention FPS drops, stutters, and laggy input on older rigs, making the game less playable on low-end hardware.

Runs well on Steam Deck: Multiple users report the game works on Steam Deck without issues, indicating solid compatibility on portable hardware.

Input responsiveness problems: Some players experience laggy or imprecise controls, affecting shooting and overall response times, especially on weaker hardware.

Droid AI movement is clunky: Feedback notes that droid AI and character movement feel clunky, with a specific bug where droids sluggishly approach painted walls until restart or death.

Limited graphics options: The game offers only basic graphics settings like resolution, motion blur, and image effects toggle, lacking FOV or brightness sliders.

Recommendations

Recommended for Portal and puzzle fans: Many reviewers recommend this game to fans of the Portal franchise or puzzle games in general, citing enjoyment for puzzle lovers, Portal veterans, and casual players alike. They suggest it fills the void for those missing Portal or similar 3D puzzle games.

Worth buying on sale: A common recommendation is to wait for a sale before purchasing, as many feel the game is not worth full price. Some suggest buying it on sale or at a discount to get better value for money.

Avoid or not recommended: A few reviewers advise against purchasing the game, even on sale, citing reasons such as frustration, lack of quality, or better alternatives in the genre. Some suggest it might only be worth it if obtained for free or at a very steep discount.

Cautious recommendation with caveats: Several reviewers give a cautious recommendation, noting that while the game has merits, there are significant caveats such as lack of undo, timing elements, or frustrating sections. They advise trying the demo or being prepared for these issues.

Not worth full price: Multiple reviewers state that the game is not worth its full asking price, with some recommending to wait for a sale or buy at a discount. The value proposition is questioned relative to gameplay length and quality.
