yea good
best game ever
this game delta-ruined my relationships. 100/10
This game is AMAZING! From story to gameplay, it's all so fun and interesting. It has an amazing concept, amazing character (seriously, it's impossible to NOT get attached!), the MUSIC...It's such a comfort game. Bosses are challenging to the perfect degree! Not frustratingly hard, not boringly easy. Well...the secret bosses on the other hand...yeesh.. But the story isn't like anything I've ever seen before! It's the type of story that anybody could be interested in. The game itself has the perfect balance between Sweet, Funny, Creepy, and downright Disturbing and I LOVE that.
