Project overview

A physics-based merge puzzle where players drop cute fruit balloons, combine matching fruit, and work toward the largest watermelon. Fruit progression, combo scoring, a danger line, best scores, and rankings support both quick play and ongoing competition.

Challenge

The physics-based puzzle needed to be understood immediately from simple controls while collisions and merge judgments remained stable as fruit accumulated on the board.

Solution

We used Flutter, Flame, and Forge2D to build drag-and-drop placement, physics collisions, merge rules, progressive fruit growth, combos, danger states, and ranking flows.

Result

Watermelon Balloon launched on iOS and Android with a repeatable loop that connects short casual sessions to high-score and ranking competition.
