! Exploding Paintballs ! 2.2

!Exploding Paintballs! is an arcade game that utilizes tilt sensitivity to control floating (blue and green) and sinking (red and yellow) paintballs. When specific color combinations of paintballs come into contact, they link together and, upon completion, trigger an explosion accompanied by realistic sound effects. The color combinations leading to explosions vary at each level.

The game features a Game Center where players can track their performance on leaderboards displaying metrics like completed levels, number of explosions, best completion times for specific levels, and overall best completion times. Players can compete with friends on Game Center to achieve the most explosions or to be the fastest to reach 10 explosions on single or all levels.

Players control the game's gravity by tilting their iPhone, iPad, or iPod Touch. Alternatively, touch movements can be used instead of tilting for gameplay.

Each color combination triggering an explosion produces a distinct sound effect (such as gunshots, crashes, and bombs). Sound effects can be disabled or replaced with vibration feedback.

The game consists of 8 free levels - 4 with walls and 4 without. An in-app purchase unlocks an additional 66 levels - 33 with walls and 33 without walls.

!Exploding Paintballs! is grounded in a kinetic simulation that leverages the device's accelerometer and adheres to realistic physics principles including buoyancy, inertia, viscosity, Hooke's Law, and color confinement. To ensure precision and stability, it applies a modified-half step Euler's Algorithm as outlined by Feynman (Lectures on Physics, Vol. 1, Ch. 9, P. 5) and Cromer (Am. J. Phy. 49, 455 (1981)).
