Short and sweet, pretty solid controls, and the concept is pretty fun. I also like that you had infer what the new key bind did from the obstacle in front of you instead of it being given directly. You could have taken it a bit further by adding more controls like attacking or dashing and then have the player chain those together, maybe have them change as a damage penalty - but the time constraints are understandable. I do think that the presentation is holding this one back quite a bit though.
