I like it! Definitely looking forward to this one, though a couple small gripes I noticed in the demo for your consideration:
1. I really wish there was a way to remove the 'acceleration' on the mouse movement, so it could just work like expected - maybe it's intended as a balancing mechanic, but it just makes it frustrating not being able to use my mouse the way I'd like in such a fast-paced game.
2. Probably won't stick around either way, but there's a bug where dying or otherwise starting a new run locks the tutorial popup for movement permanently on screen, which is a bit annoying in general but importantly also blocks upgrade text.
This is all in reference to the Steam version demo, if that's at all a different build to here.
