Cool game, I like how it allows you to continue playing even if you die.
My feedback is that it can be a little too easy to miss coins especially those from a boss fight. I'll also admit I skipped straight over the main menu as that was far too cluttered and then only read I had like 2 other weapons that I didn't use.
I love the music, but the game just ended and cut to menu just as it was getting really good.
