Description
Core Gameplay
Each level presents the same floor at two different “strata” (e.g. morning vs evening, furnished vs empty). Find eleven differences caused by time or usage changes. The stack grows by one stratum per level completed.
Level & Content Design
Thirty levels, each with a unique time‑based theme: pre‑renovation / post‑renovation, daytime / night‑time (lighting changes), occupied / vacant. Difficulty is high due to lighting and shadow variations. No automatic updates.
Visuals & Experience
Rich, atmospheric 2D art with dynamic lighting simulation. The two strata are presented with a fade‑in/fade‑out slider for comparison. The game is visually impressive but requires moderate device resources.
Key Features
A “light equaliser” tool that normalises brightness between the two images, revealing differences more clearly (use limited to twice per level). No timer by default; an optional timer mode is available.
User Value
Teaches players to look past lighting and context changes. Useful for anyone interested in visual perception (no medical claims).
Usage Scenarios
Relaxed but focused evening play, artistic observation practice, or as a unique gift for puzzle lovers.
