The field of view is too zoomed in, and the text is too small, I couldn't read it. An indication would have been good when the bindings changed, maybe a sound effect, or a countdown. The could have used some more sound effects, like a sound when the bindings changed. Sometimes I couldn't jump because the was no binding, and the ',' character is not at the same place at every keyboard layout, so there were some weird controls.
If these were fixed it could be a decent game.
