art is cool. and the ending is good.
I definitely would have made more of a point about the down button being the key to winning though. like even in the button layout, for example - instead of having jump assigned to every button, have A jump and B down so the player knows there are 2 functions. I only read your hint by chance as I was about to quit, so went back and played again.
only other thing I would say is it would have been nice to have a tune to jump to
nice work
