Core gameplay
Blocks fall from the top, but the well has a movable ceiling that lowers every fifteen seconds. You must clear rows to push the ceiling back up. The game ends if the ceiling touches the highest block.

Level and content structure
Endless mode only. Ceiling descent speed increases every thirty seconds. No level selection.

Visual and user experience
The ceiling appears as a horizontal grey bar. Blocks use warm earth tones. The bar moves smoothly without stuttering.

Features
A warning colour change (green to amber) signals the ceiling will drop soon. No sound or vibration alerts.

User value
Introduces time-based row clearing without a fixed timer per move. Encourages efficient placement habits.

Usage scenario
Short periods before a scheduled task begins.
