Cool concept, and there are some good ideas with the level design in some places. The controls are a bit janky though, and the timer should probably be a lot bigger, I missed it completey at first and was very confused about why I got sent back to the beginning seemingly at random. I can't say I'm a fan of the music, but that's more subjective.
Overall, the concept could be fun with more polish, but it's a bit rough in its current state unfortunately.
