Very cool game, with exceptionally good looking art for a game jam! There were a lot of subtle details that showed me the polish and understanding that went in the overall design, such as the red flashing for anything that is a hazard, a generous small hitbox for the player, indicators for where the hazards would be coming from, etc.
The difficulty scaling was great, although at some point later in the game, I was so heavy that I couldn't get out of the way of some obstacles in time even when knowning where they would come from (but that could also be a skill issue). But the difficulty progression doesn't just add more hazards but also changes the formula a bit each level to keep things interesting.
A small thing btw, I didn't completely understand when a timeout would become a game over, I just saw I died at a score of 228.
Anyway, love the game, impressive for such a short time! :)
