Really good idea and concept! The nature of the puzzles is more of trial and error, but I love this reverse engineering approach. It really makes you think in a different way than traditional puzzles. The music was calm, the graphics simple, some animation and sounds would have really improved the experience. The only critique I would have (in case you want to futher develop the game) is that I've encountered a little frustration when moving the blocks, as they didn't fit easily in the holes, and sometimes that "human" had some issues walking over them. But great creative work, I really enjoyed the experience and the creative puzzles.
