Game Looks great. Really nice feel to it. Nice puzzler idea as well.
Only issue is the lack of being able to rotate the "mirrors" in both directions, though the arrows on it seem to suggest I can. They're also to slow, I don't want to spend time waiting for it to turn around, especially when its just gone past its mark.
Those 2 issues are quite fixable, and with that, i think you'll have a great game that you could easily release. Well done!
