Reverse Stack: Undo Gravity, Remove Blocks

Core Gameplay
The game starts with a fully built tower that reaches above the target height. However, the tower is unstable. Players remove blocks one by one in reverse stacking order (top to bottom) until the scale becomes perfectly balanced and the remaining height is exactly the target. Removing the wrong block causes collapse. This reverses the typical stacking challenge.

Level & Content Design
210 levels, each starting with a different pre‑built tower. Later levels have towers with hidden internal blocks (you cannot see their weight until exposed) or blocks that are fused together and must be removed as pairs. Includes a “History Mode” where you can replay any removed block sequence. All offline.

Visuals & Experience
Antique blueprint style – yellowed paper background, dark brown block outlines, weight values handwritten‑style. The removal action is a gentle dissolve effect. No music; only soft paper rustle sounds.

Key Features

Removal Preview: Hover over a block to see how the balance will change if removed.

Undo Removal: Reverse the last removal (up to 5 times per level).

No Time Limit: Purely turn‑based; ideal for thoughtful play.

User Value
Teaches structural analysis and reverse engineering. The removal mechanic feels like solving a mystery rather than building.

Usage Scenarios
Excellent for analytical thinkers during coffee breaks, or as a collaborative puzzle for two people sharing one device.
