Nice game!  Some of the jumps are tricky cuz they are too close together or because I can't stop quick enough.  I like the animations and the sounds.  Good work!  RE: the rules, I don't think you would get disqualified for using a non-pixel title or menu IMO but the sub-pixel movement would more likely.  You can try using a Rounding function like Round() in your movement function(s) to get it to stay on a grid.
