Creative use of the theme - I could picture this being somewhere in Edmund McMillen's book of ideas, and the art style definitely had a kind of 'meat boy' flair to it!
The difficulty curve in the level design was pretty drastic - I felt proud getting halfway through, but it could definitely stand to be a bit more forgiving.
Overall, though, it's a good game! Needs a bit of refinement but it has an impressive number of mechanics and, again, fits the theme nicely.
