Interested in seeing where this goes. Especially for the vampire Yuri route when you finish that!
The main errors I found with Demo 1.0 were grammar or spelling related and sometimes the names didn't appear over the text right. Either the wrong person was speaking or didn't have a name attached to it at all. Not sure if I could efficiently point out every single time those two errors occurred but those were the main things I noticed.
Good luck with this! :)
