Awesome! The visuals and the sound design and music were excellent - the movement felt good (although walljump spamming could be improved), the dashing effect was just so... tasty! I found a pretty serious glitch that I would sometimes not damage enemies I'd attack with the melee strike.
It could be that I was just dealing too little damage to kill them, but getting a bit more visual/audio feedback when the melee hit connects would benefit your game - so it would be clear when you hit them or not. Normally I'd go on about all the things that you could improve, but your entry is just really solid. Very good job!
