Description
Core Gameplay
Two side‑by‑side floor cross‑section images are shown. You have 60 seconds to find at least four differences to pass the level. Each correct difference raises the floor‑stacking column by one layer. After passing, the next floor type unlocks.
Level & Content Design
Fifteen quick levels, each featuring a single floor style (e.g. ground floor, first floor, second floor). Differences are obvious – for example a missing window or a different door colour. The level set is fixed and not updated.
Visuals & Experience
Bright, cheerful vector graphics. The game area is centred, with functional buttons on the sides. Full‑screen mode is available, and clicking produces a bouncy animation.
Key Features
A brief tutorial animation is included. A “reset” button restarts the current level, clearing all found differences. Hints are unlimited but will lower the level completion rating.
User Value
A quick way to train observation speed and short‑term attention. Works well as a daily mental warm‑up.
Usage Scenarios
Morning brain activation just after waking up, or a few minutes before starting work.
