Thank you for your feedback, I actually wanted to implement procedural music, but I didn't have time and the same about he second one.
Btw these are few other bugs you could find;
-missing rooms
-glitched enemies textures
-glitched projectiles
-diagonal movement is faster
-glitched boss fight
-if you heal when full the hearts will glitch+so u can have infinite health if you have enough heals)
-inventory glitches when full
