Description
Core Gameplay
Each level has a “cantilever” twist: one of the two images is mirrored horizontally or vertically. You must find differences while mentally reversing the mirrored image. Differences count only when correctly identified relative to the original orientation.
Level & Content Design
Twenty levels, each with a different floor layout (open plan, partitioned, L‑shaped). The mirroring changes per level (left‑right, top‑bottom, or diagonal). No content updates.
Visuals & Experience
Colourful but clean vector graphics. A small icon in the corner indicates the mirroring type for that level. The interface includes a toggle to show a faint reflection guide (optional).
Key Features
A “mental rotation helper” overlay (dotted axis line) can be enabled. No time limit; the challenge comes from the mirroring mechanic. Three hints per level that remove the mirroring for five seconds.
User Value
Enhances mental rotation ability and spatial reasoning. A unique twist that refreshes the spot‑the‑difference genre.
Usage Scenarios
Cognitive warm‑up, co‑operative play (one person describes the mirrored image), or as a novel party game activity.
