The game was easy to pick up. I like how you start with just jump, and add the "crouch" later. The way you have the sprite on its side for "crouch", I think it looks more like a slide, than a crouch, though "crouch" still conveys the intended use. I used the mouse to start, and the log in message stayed at the top until I clicked the X to close it. The message says "Press to start", but not what to press, so I clicked on it. Maybe specifying what to press would help to direct focus to the keyboard/controller.
