Love the art style and the gameplay concept, if it were to be longer some sort of charging mechanic or risk/reward would be nice, and I enjoyed how the speedrunning aspect was incorporated.
Some notes:
-When you reach the end, the high score timer slowly lowers, and the overall timer doesn't stop
-The game stops very abruptly, something more climactic (e.g an animation or some exposition to let the player know why this is significant) would boost the experience for me.
A great experience overall :)
