Fun game overall, however there is a bug
Very addiciting and there's a good rush and stagerty required at higher levels. However, my guess is that the levels do have some random elements to it that can make a level impossible.
The one I ran across was during level 9, during the initinal launch, there wasn't a single planet that was close enough for my mouse to land on and begin it's ascent upwards. And to make matters worse, once the mouse hops from the pad, he CAN'T directly return...EVER. So my mouse got stuck bouncing up and down in an infinite loop until the level essentially timed out. Perhaps allow the mouse to be relaunched, even at a slight angle without resetting the game would be a nice feature.
