I'm annoyed at myself because I cheated a lot of puzzles, but even with that it was good. I'm reviewing this well after I played it, so my memory is a bit fuzzy, however the parts I do remember were either really good and made some interesting use of the mechanics, or were extremely odd. I didn't struggle on this puzzle like others did, but there was an odd puzzle that broke the game's own rules. Play it if you have way too much time on your hands and a good sense of spatial reasoning.
