Surprisingly good for a game with one control lol. Had quite a bit of fun but sometimes felt a little bit too much like a precision platformer with one slightly missed input causing you to restart the whole run. Could be more fun with the addition of some sort of momentum boost like a slide or just a run button in your current direction and maybe adding some sort of hard stop control (ik against the theme of this jam) could be cool as well because sometimes it's nice to stop analyze a jump instead of being forced in and possibly costing you the run. Both of these would maintain the directional momentum and just add more dynamic movement but just suggestions. Overall pretty great game though and well done for having a single control and still making it fun.
