This was an amazing first chapter! Already in love with the world and the characters, I can tell you put a lot of thought into the setting and its inhabitants! Really excited to see how the story develops!
The party deserves a separate mention, you did an amazing portrayal of what's it's like to gradually get more and more wasted haha.
Mechanics wise, "All sex scenes are avoidable" is something more games should implement, give me that sweet, sweet player choice!
Looking forward to chapter 2!
