Physics are a bit... weird. Sometimes the balls will stick to surfaces regardless of direction and momentum, other times they'll fling right off and fly away.
I also somehow broke the mute button so the sound plays constantly. I've had a couple levels just freeze, but the main menu button still worked so I exited and continued.
Just feels unfinished.
Has a very eerie "other worldly" feeling to it, but then again I suppose it really is another world. 5+ for originality. You're a very gifted person. All of your games make me think and feel things I wouldn't have on my own.
