Excuse me for a few questions.
This demo has limited gameplay content.
For example:
There is newgame+ in the demo.
They mention something about going with some cultists.
You can find the site of the hidden alley, which they also mention in the comments.
about the murderers.
it only has 1 ending
Will they have discord?
and with your demo file, I go to the patreon and get the game. I could have what I already achieved or I would start from 0.
So as not to waste time on the demo and go for the full game.
Finally, while games that focus on sexuality and fanservice can be easy to attract; When you come across games like these, the only thing you can do is be grateful and wait for the game to finish since the themes of cards, fetishes and endings make you want to achieve everything. Although it has its errors, I am sure they will be fixed; to fully enjoy this great game. all the best.
