Very nice!
Beat both bosses (snake on 2nd try because it the controls weren't immediately clear and I had to figure out how to damage him). The boss fight mechanics (and especially the visual design of the snake) were great, and it was unfortunately over all too quickly.
Technical note, I couldn't play it on my widescreen monitor (2560x1080) the top and bottom of the screen where cropped off, and I think on my other monitor (4k) the snake may have gone out of bounds, not sure if that was intentional or not?
Otherwise really nice, precise and reactive movement on the character and great music, overall really enjoyable game.
