neat, here are a few bugs i noticed
music ends right as you start playing, dunno how to solve that
you can still attack when your holding onto a ledge?
you could solve that by adding a sprite of a char swinging while on a ledge or something
if you jump while holding down d and then press a, or vice-versa, it breaks the animation.
also the background is unfitting, but it might be temporary?
otherwise it was nice, better then what I could do.
hope you end up finishing the game
