I liked the concept! The arts are cute and I like the concept. Must be horrifying, talking casually with someone knowing full well that the person interact closely with time then suddenly their mannerism shifted. Then, again, that ended up never happened! The only prove of that ever happening is her memory. Cool!
The boss fight was reallllyyyy tough. Wish I could skip the dialogue before the fight all together. Feels like I reduced the lifespan of my keyboard by 10 months fighting her.
Overall, fun and challenging game with story on top!
