Ohh, I wasn't planning on it but a glossary is a great idea so I'll get started on that.
The only stats being tracked with the MC are regarding how his personality will develop. I'll consider tracking some 'combat stats' as well to influence some events, it sounds like an interesting idea if I could implement it well. But the MC will see more action regardless, so no worries on that front!
I currently have 16 'main' girls planned for the story, but I'm currently thinking that 24 will eventually be the maximum I can feasibly juggle when all is said and done.
Thanks for the feedback! Glad you're appreciating the project.
