A lighter and simpler version of the famous Slither, Circle Game is an addictive game itself. The objective of the game is to grow your circle by eating smaller circles that are running across the board. Colliding with a larger circle results in a failure.
The game features a similar collision concept as most games, the difference is just that the reference object is the mouse pointer.
Be warned though, because the size of your circle is getting monitored and that the floating circles around it are also getting bigger. So don’t think the game will eventually become too easy when in fact, it won’t.
