I had a difficult time getting started. The tutorial screen is very difficult to read, and it isn't very clear what the goal is because of the way the words wind around the screen. Lining up directions in a more traditional way can make your guide screen much clearer and makes it easier for the player to understand your game.
When I started the game, I could not get past the first platform. The instructions briefly said to "Press F", but when I did, nothing happened. Then I took one step forward, and I died. I tried all the buttons that were mentioned in the tutorial, but nothing happened. Having some more play-testing in the early part of the game could really help you refine your game!
