Nice Looking game.
There are some of my personal feedbacks
--> I think the environment is kinda too dark
-->May be reduces some jump floatiness.
-->Some effects like dash and slash, it's dark, I suggest you should make them some bright colors or something. so that you can see them properly. Might be some particles when moving.
-->Better enemy AI, some of them got stuck.
-->Quick attack
Considering This is only 7 days of work. It's good. :)
