Another one?
Seriously, another portal clone/gravity game? This just reeks of lack of inspiration. Your presentation is nice, and your game responds well enough, but it's not quite enough to make up for massively annoying techno music, the super annoying "look at me being clever" voiceover and the done-to-death concept.
With a solid concept you could really make something great. Get some friends and have them do some playtesting next time, not just for glitches and bugs, but for "fun-ness."
