Scratch version

Antimatter is a game taking place in a particle accelerator. You are an experimental antimatter particle (represented by a green triangle) being sent to your inevitable collision with a matter particle. You must avoid these normal matter particles (represented by red triangles) for as long as possible. Along the way, you can also collect other Antimatter particles, which will give you points or power ups.

Yellow: 5 Points
Green: 20 Points
Blue: 25 Points, and temporary slowdown of the game
