This is pretty neat so far! I would like to see more. I got stuck here, though, and didn't see a restore save option when rebooting. :/

I beat it. Wasn't sure if there was anything after the credits. Short and sweet. Definitely could do with some fine-tuning both of collision-detection and general design. For example, more intentionality on when and where the blades are swinging. The demo as-is also feels somewhat linear--this feels like it could easily be a buildup of a standard stage-based action-platformer, which isn't bad but does feel a bit off-genre here.
