As others have stated, the atmosphere is definitely unique. One problem I had was being unable to tell which parts of the environment the player is supposed to be able to interact with, and which parts they can't. In the third level, I had to just watch the attached video to figure out that you could walk past the dude's legs, but not his chest. In the first level, it took a bit of trial and error to figure out I could jump on the plant. A more clear delineation between what is background and what is foreground would help a lot. Otherwise the puzzles were cute and well designed. Good job!
