Features of Musical Physics Simulation App

BPM-Based Speed Control

Adjustable BPM slider in the range of 60-180 BPM. Music genres are automatically displayed based on BPM, and ball speed changes according to musical beats. Features BGM playback and BPM-synchronized playback rate control.

Intuitive Tap Controls

Place obstacles by tapping on the screen. Precise coordinate conversion ensures tap position matches obstacle placement. Obstacle size changes based on tap duration (20-55px). Four obstacle types (Fire, Ice, Electric, Poison) provide diverse experiences.

Physically Accurate Simulation

Balls move continuously with uniform motion without gravity, and reflections from walls and obstacles are physically accurate. Natural reflections based on collision angles provide realistic physics experience. Features trajectory display and real-time speed adjustment.
