Graviton is an avoidance game that Sam Gynn created for the 18th Ludum Dare competition. You move your cursor with the mouse, and points are scored by getting the enemies that chase after you to collide with each other.

A multiplier bonus is awarded for getting circles of the same colour to collide, although you won't be concentrating too much on it when the screen is filled with enemies of all sizes and colours. There's also no way to turn off the annoying music at the moment, and though the developer had spent an entire day playtesting Graviton, the game still has a tendency to crash both my IE and Firefox browser windows when the score goes past 2000 points.
