It's a neat idea for a game with some very nice art, but I kinda found it a bit slow to get through the puzzles. I think it would be nice if maybe you could alternately use wasd for movement, and also, it was a bit slow to use spacebar to go into psychic-collar-manipulation mode, and that maybe it could be mapped to right-click instead? And perhaps the rotation speed of the blocks could be increased to make it easier to quickly spin them around to get the correct routes. (especially when you accidentally dive off the building after coins and find yourself at the bottom and have to rebuild all the way back up to the top >.<)
Well, best of luck with your games!
