Yo! This game is quite a lot of fun but I got stuck on the third puzzle. I might come back and try and solve it. One complaint I have is that the background audio is kinda annoying because it's a repetitive loop. I suggest having something longer and less repetitive or alternating between different shorter tracks.
I also think the cubes moved pretty slow, the animation should be faster. The level design is engaging. I like cloning myself and just trying to get stuff to line up. The sound effects are cool. One suggestion that might be worth considering is adding a meaty blood effect when you move onto the ground, like in Super Meat Boy, but it might be distracting so worth experimenting with.
I enjoyed this game. I rated it a 4/5 for Creative use of theme. I might come back and play more of it and the later puzzles.
