Wow, this game is really fun! And hard...
One thing, though: I find it really hard to see my character, which is especially a problem for the trickier segments. The controls also felt a bit stilted and awkward, and could be improved greatly.
Additionally, I think the "only one life" is a bit annoying; I know it goes with the theme, but I think the "only one level" is enough (I got frustrated after dying a lot and just quit).
All in all, though, this is a fantastic entry! Excited to see what you'll make next. :)
