This was fun, I was going to complain that it was to easy but then my dumbass got stuck on the forth level for ages! After that the puzzles were really good, great design and some interest elements thrown it to really spice things up as the game went on. Although there was nothing truly mindblowing I enjoyed it nevertheless.
Edit: Oh and I had a few bugs where I suddenly couldn't move as well as the sound skipping (nothing major though!)
