About the Game

Topsy Stack is a bright physics puzzle game about balance, timing, and playful problem solving.

Drop colorful objects onto the stack, study their shapes, and build a stable tower without letting everything tumble. Each level introduces a fresh arrangement, asking you to plan the order, place objects carefully, and recover when the tower starts to lean.

Designed with SpriteKit and Objective-C, Topsy Stack keeps the action simple to learn and satisfying to replay. Short sessions make it easy to jump in for a quick challenge, while later stages reward patience, precision, and a good eye for balance.

Features:
- Colorful object-stacking puzzles
- Physics-driven movement and collisions
- Carefully paced levels for casual play
- Clear touch controls
- Optional rewarded ads for supported revive moments
- Support for iOS 13 and later devices
