Wow using procedural generation is impressive :o Using deaths as a currency is an interesting idea. The camera zoom when we draw our bow is so cool :D My feedback would be that after shooting the arrow camera zooms out instantly and that is uncomfortable it should be smooth :d Also the stairs sprite is on top of the player sprite you should change the layers :D Other than these small issues i would like to see this game with more content and more things to explore great job well done :D
Note:I would be happy if you could check out my game as well :d
