I'm sensible of motion sickness and sadly I couldn't play for too long your game, but! I could play more than enough to feel what the game is about/how to play (and die :D).
Just before I forget, maybe I didn't find it, but it'd have been cool to have a keyboard shortcut to continue between levels (and if there's one, add it on screen then I guess :p) and I agree on the F key too.
The game is really juicy, I had quite a few questions about things happening, mostly understood everything except that red dice and now after reading the comment, I get what happened :D.
The feeling of stabbing/dashing was really great, I find myself happy to see an enemy => "STAB YOU". It's just really satisfying to play, you feel strong and powerful, well done!
