Definitely a unique and interesting concept! The artstyle is also great! But I think the game is missing some music.
I would suggest to make it so the player dashes towards the mouse cursor as it has been already mentioned before. Also I noticed that sometimes the dash distance was sometimes short and at other times it was longer (I am thinking it gets longer when dashing diagonally). I would suggest making the dash distance consistent.
Overall an awesome game! Great job!
