This is not a hater's comment, I just tried to make a constructive critique.
Honestly, I expected a better game. I can understand the graphics are just placehoders, but it was quite forgettable for me. Don't think of this as a hater's comment, I think this can make a better game.
I think Carmilla's fans would expect an adaptation of the book - I can tell since my girlfriend is such a big fan of Carmilla, and was really dissapointed to know it was about the web series - and as a reader, I also think it'd be better too.
I don't know if the dialogues are going to stay as they are, but if they do, I suggest more development, as in the story as in the characters, since I didn't actually understand the plot because I found it quite rushed.
Just some suggestions from a VN fan, cheers with the game! I know it can be better.
