Wow. Impressive work in compiling them resources together, for starters. O_o The Donkey Kong animation seems a little rough in terms of speed(maybe too fast, or the player object moves too slow??). Love the little aesthetics like the moving trees in the background and such.
This is a good start.
Any idea on what the story is? Or what are you going for with this? Welcome to ZFGC, by the way.
