Very cool game ! I liked the concept & the visuals.
Tiny feedbacks :
It would be a good thing to be able to access the next level without having to use the mouse to click the button, since the mouse is not used anywhere else in the game.
Dashing to press the buttons is a very good idea but a bit fidgety. Several time I ended up being to close to a button before dashing and then button didn't press. making it so you can dash on the button even if youre standing right next to it would probably feel less punitive.
Apart from that, It's a really good game. Great job :)
