The game was really cool. The player movement felt nice. The effects were awesome. Dying felt very punishing because I had to redo all of that, but maybe that's just the style of this game, so no problem. The sawblades were spinning too fast that you couldn't see the original sprite anymore. Maybe that's because I have 144hz display, I don't know.
(took the picture from my phone because it's how it's displayed, so a screenshot wouldn't work because it would pause on a specific frame)
Also, you might want to turn off antialiasing on the font so it is more in theme with the pixel art.
All in all, great game!
