TowerStack moves a block left and right at increasing speed. Tapping drops it onto the stack below. Overlap determines the new block width — overhang is cut off. A perfect drop (within 4px alignment) increases the combo multiplier up to x6. Missing completely costs 1 drop. Camera scrolls up as the tower grows. Score is based on overlap width times current combo.
Mechanics are explained on the in-game start screen. Difficulty parameters may be adjusted in future updates.
