The difficulty is one of the tougher things for me to balance. I wanted it a bit difficult but not unbeatable. I made it so I'm pretty good so it's hard to gauge and no one had time to play test it for me. I was worried about the jump and tried some things to help out, but I didn't have time to redo too much. I agree that in game controls would have helped a lot.
I'm glad you liked it and thanks for playing and thanks for your feedback!
