Good news! Collider is now available on the iPhone and iPod Touch! You can download it from here: http://colliderthegame.co m/c/CollideriPhone
After completing my previous game, Block Drop, I wanted to do something completely different so I started experimenting with the Box2D Physics engine. Once I became comfortable with it, I started fleshing out the core elements of the game by introducing the rolling balls and then coming up with interesting obstacles and gadgets for them to interact with. When the idea came to make the balls annihilate each other, Collider really started to take off.
All of the music in Collider is dynamically generated and each level has its own unique composition.
I really enjoyed making this one and I hope you enjoy playing it!
