Very polished and fun to get into. sadly very repetitiv gameplay and for me way too much hp on the boss. but i guess thats no problem for people who enjoy this kind of combat (maybe i was just to bad highest damage i dealt was 300?). For me half the HP would had been enjoyable since there is not much else going on but doing the same thing over and over again.
The story was entertaining and super well executed (some one references in the artstyle?). The sound was smashing but due to the long hpbar also somewhat repetitive.
Sorry if I sounded harsh im sure you got a good amount of deserved compliments already so im just trying to find things you might want to work on in the future.
