thanks for pointing that out, it does seem to reach a point where the game kind of plays itself and there isn't anything to do. after the jam i'll add something to make the game more difficulty after reaching a 1 minute in.
this is a really cool idea! i like how you adapted the theme (going too fast makes you die), the audio was nice to listen to, and the game is just overall quite fun to play. one thing that would make it more engaging would be to add more variance between levels, since they all felt more or less feel the same.
