I really like the environments and the low-poly look of the boss! Combined with the more HD texturing and lighting it creates a really unsettling "uncanny valley" effect.
This is very much not my genre, and I got frustrated because I need to attack the boss to heal but I also can't attack just whenever I want because I'll be stuck in an insanely long attack animation (could definitely be shorter) and get hit and die.
All that being said, leeches are adorable so it feels good to be able to play as one.
