Nah i'm at the third level and the running robot is somehow giving me" backshots" while not harming me, and i'm stuck there perhaps in a kind of flying animation...
Third level has it seems some bumps which seem to affect player movement in an unnatural way.
Revising that would make the game way better.
Either erase the bumps, or program it so the player can step up automatically short height (typical stair movement code)
Overall very cool and polished, but yeah the movement could use more polish and if you do polish it then the game goes way higher, since movement is after all the main thing the player experiences all time...
