From the Experimental Games Department comes this fun little diversion.

What happens when a planet living on the edge loses its identity? It goes mad and releases its fury on to the unsuspecting solar system. Your job is to control the huge baseball bat that is circulating Pluto. Try to hit the meteors so that they will cause damage to other planets.

Not a flash game, but a downloadable executable. So yeah, windows only.
