StackUp: Reflex Game

Stack bars as high as you can. Time your taps perfectly to keep the tower alive. Unlock hidden modes. Climb the leaderboards.

Tap. Stack. Climb. A bar slides across the screen. Tap to drop it. Land it clean and your stack grows. Miss the edge and your bar gets shorter. Drop it too far and you lose a life. Simple rules. Tight timing. One screw-up away from disaster.

FEATURES
