Great game. Didn't play it through yet though, I'll have to give it another try later.
The music and soundeffects fit the gameplay really well.
I would have wished that the screen with the controls would have stayed until you press any key or that there was an option to show this screen again. I wasn't fast enough to memorize all keys. And when I had to dash for the first time, I had to open a second tab with the game to find out I had to press J :D.
All in all, really fun to play. Well done!
