Very cool. I'm not sure whether the game is easy, or I'm just good at this kind of thinking, but it didn't seem that complex to me.
I don't think that's a bad thing, but maybe there could me more mechanics involved, like rotating mirrors to reflect a light onto a switch, or springs you have to stretch out and release or something?
But it's a good brain bender and it's fun to analyse these mechanical problems and see everything working as it should. I wish there were more puzzles!
