Was OK
The movement was odd. The speed wouldn't stay consistent. It would be nice and quick for a little stretch, then it would nearly stop completely (even when my mouse was far on the edge) like a pulsing, which was maddening. It also seemed to move very slowly overall. In a game like this, I want to just zoom around and explore, find little hidden rooms full of poweups etc. The controls are vitally important to that and here they detracted from the experience.
I liked the idea, even though I've seen some similar stuff before I think it's still fresh. the graphics were alright. Overall not a bad game. There always seems to be one thing that makes or breaks a game for me, though, and here it was the inconsistent controls/pacing of the game.
