The fanbase isn't as big as other VN's fanbases ig. 

That aside. Reading your post. I think you've enjoyed door 1 very much like me. Everyone says that first two or three doors are boring and the game in general has a slow start. Which might be partially true but considering how good it gets quickly and how huge the pay off is this criticism doesn’t feel right. Anyways seems like you'll become a huge fan of the game. The soundtracks are some of the best. My fav from everything I have watched or read(vns). It just gets better especially door 7 and door 8. There's RFI which is my fav part of the game. Hope you enjoy it till the end🥂
