Description
Core Gameplay
Every level shows a “before” and “after” image of a base floor (the lowest floor of a building). Five changes have been made. Your task is to revert the after image to match the before image by tapping each change. Each correct tap stacks one base layer.
Level & Content Design
Thirty levels, all featuring base‑floor elements: foundations, ground slabs, entrance steps, and utility areas (decorative only). Difficulty increases by making changes more integrated into the scene (e.g. changed tile pattern, shifted handrail).
Visuals & Experience
Realistic but simplified 2D drawings with earth tones (browns, greys, greens). The colour palette is intentionally calm. Animations are subtle – items gently fade when found.
Key Features
A “comparison slider” lets you swipe horizontally to see the two images overlap. This feature can be turned off for traditional side‑by‑side play. No hints are provided except the slider.
User Value
Encourages meticulous observation. The slider tool is especially helpful for players who struggle with side‑by‑side comparison.
Usage Scenarios
Lazy afternoons, travel by aeroplane (offline mode), or as a co‑operative activity where two people share one device.
