Pretty cool, once I got a hang of how the puzzles worked.
Simple concept, really well executed. The backtracking was a nice touch. The long blue elevator was a nightmare. :P
"I'm sorry but I absolutely have to do these things before saving the world." That was quite the experience. The intro was awesome. Being able to go back to bed at the end made it for me. :)
Really fun. The moving pillars in the eye boss' room really send you flying. :P
