Nice! this was fun. The attacks were cool. Some stuff I think could improve it is making the enemies fly in the opposite direction you are slashing from because a lot of time I would slash and they would immediately hit me after I came out of it. Also, I kept dashing in the wrong direction because my mouse was opposite my facing direction. Maybe make the character always face the cursor so you know which direction you will dash. (this might result in a running backwards animation where you are moving the direction opposite your cursor).
