Very hollowknightish:) Final boss is a big good (or rather evil?) surprise:)
The game will benefit from adding a map. But even without it there are not so many locations and they're mostly well distinguishable.
Music and sounds, controls, graphis are just fine! Only in one place in boss fight dash often was not working in one critical moment. That may be due to my laggish laptop and browser play though.
Excellent submission, congrats!
