I really like your game, the only thing that I think could be done better is that I can't tell exactly where I am supposed to go at times, adding some signs might help.
you go to the goal ring
Yes but during the level it's hard to tell if a gap is a death gap or if its just an area to fall down
if theres a dead end ahead of you and theres nowhere to go but either back or down you just go down its pretty simple
