I LOVE THIS. Ultimate Chicken Horse but as a highscore chasing roguelike? Sounds amazing and definitely should be made into a proper game.
Regarding it as a game jam game, I think the initial score requirement of 100 is way too high. I tried like 8 runs playing "normally", building tricky courses but still couldn't get 100 at all. Then I just thought about and spammed Spikes, and the game became trivial. I get that balancing is hard in a jam game, but good job overall.
