This is a really cool concept, I love how you interpreted the theme. The game looks awesome and the audio is good. The gameplay is fun, but it is a bit unforgiving. I think it would be cool to give the player some sort of health or something just to avoid having them explode the second they touch an enemy/spike. But once I got the hang of it, it was pretty fun and I beat the final boss (though it is a bit weird that you get immediately kicked back to the main menu).
Overall, a super creative game with great pixel art and fun gameplay!
