Description
Core Gameplay
Unlike single‑floor games, this title requires you to spot differences across three simultaneous floor layers (ground, first, second). Each layer has its own set of differences. You must complete all layers within a combined time limit to stack the entire three‑storey section.
Level & Content Design
Twenty levels, each with a different building type (townhouse, small office block, public library branch). Each level introduces more differences per layer as you progress. No updates after launch.
Visuals & Experience
Isometric 3D‑like visuals with layered transparency. You can toggle individual floor layers on/off. The game is optimised for mouse/keyboard but works on touch with on‑screen layer buttons.
Key Features
A “layer sync” tool temporarily highlights differences common to two layers (rare). Unlimited attempts but each failed attempt adds a 10‑second cooldown before retry. Offline saving.
User Value
Trains divided attention and multi‑source comparison. The three‑layer format is unique among spot‑the‑difference games.
Usage Scenarios
Challenging solo play, group puzzle solving (taking turns per layer), or as a mental flexibility exercise.
