Very nice! I am starting to get the hang on it and it just end there.. I want more ;( Also the ending XD
Anyway, the idea is great, the combat is not bad in my opinion, nice music that works with the style, good job!
My suggestion would be 1) make the combat hint (Q,W,E,R) layout horizontally, 2) Maybe add a brief time out before allowing the next attack input? I breeze through the final boss by just spamming buttons
