Can't even play the game, it insta-crashes no matter what setting I choose

Level 4 is so hard. The most keys I've had was 8/11 and I keep falling in.

1. Please look into adjusting the jumping mechanic. Either let us have the ability to look down so we can see how close we actually are to the edge, or increase the distance of the jump. So far, almost everytime I have attempted to jump, I get what appears to be right up to the edge of a lava field, and upon jumping, I fall in... Game over! :( 2. Please let us adjust the default key bindings. I'm used to E or F as my action button. This game requires X which is throwing me off. Not a big deal as I guess I...

Game is pretty straightforward but any advice? :)
