It's really addictive!
One thing I'd improve is the tutorial. It's a bit too subtle - I only payed attention what was on the screen before doing any movement. I didn't know there was more information after that until on my 3rd attempt. Maybe you could inform about the hazards right before the player has to face them, and make a better contrast and placement for the text.
Still there's harmony on the visuals and music, as well they stand out really well on themselves alone. Gameplay is as simple as responsive. Did you make all this by yourself?
