Nice game. Actually needs some practice to get used to the mechanics which'll obviously put a lot of people off. But definately 4/5. (It'd be 5/5 if the mouse controlled everything!)
Mime, get a pocket calculator. Put in "2 + 2 =". Keep doing this until it makes 5. Hopefully that should keep you busy til doomsday so you don't publish any more games like this turd!
I think the game would be better with some sort of inertia coded in, but the API stuf can be found here: http://www.kongregate.com/forums/4/topics/3064
Really would like to see the controls tweaked a bit. Turning to face the other direction moves you nearly a blobk width, which is very frustrating. Got themakings of a very nice game though.
As a physics demo, this is really good. It clearly demonstartes the workings of a chaotic system. However, as such, doesn't make for a game of skill. The slightest change can produce wildly different results. 3/5
