2/5 - The sprites pass through walls and bounce as if they hit a wall when one isn't there. When I kill the saws sometimes they don't dissapear, when I kill the other things sometimes they continue bouncing around inside the filled area. Once I had one of the things with tails just bounce off an invisible wall - and then pass through a real one, and fly outside of the playing area. I was glad to be rid of it, but that shouldn't have happened.
Way too hard. No brakes, and you swing wildly if you go too far left or right, unpredictably. Without better control of my 'vehicle' I have no intrest in playing this game.
