This is a super cool concept! I really like the color palette and the style in general - everything looks really nice and clean! I think the greatest critique I have is there seems to be some issues with the detection during the jump recording - I had to press space twice before it would work. Additionally, this is rather nitpicky but I don't think it's necessary to have the player press space at the end of each cycle to move on to the next action (ie once you finish recording right you have to hit space again to the jump action and then space again to record - I think it'd make more sense to just switch to the jump action automatically then hit space to actually start recording). Overall though this is a really interesting mechanic!
