Nice short concept!
It just feels a bit weird to be able to rotate once the gripple is "fixed", but it doesn't stop you from playing at all. The game is in the theme, no problems on that. It just lacks a difficulty curve, like faster scrolling with time, or ennemies, but good job nontheless!
(Important note however: being red/green colorblind, having a black character on a dark-red background makes it invisible most of the time, I could only know my position thanks to the glowing yellow eyes)
