Strongly reminded me of VVVVVV but I liked the idea of adding puzzles to that style of game. I didn't have a good understanding of when I could go through a door and when I could not - from the first room with a choice of three doors, only two of them worked. Also, after going through a door I could not go back through it, meaning when I got stuck in the corridor with spikes at the top and bottom (my reflexes aren't nearly good enough to deal with that), I had to quit in order to backtrack.
As for the puzzles, I found there was a huge jump in difficulty with the third puzzle, and being unable to rotate or change the gravity on the mirror blocks, I didn't see a good way to make it work, so eventually gave up.
