QTE aren't a good idea for a VN, better if you give the player the option to play it really easy or change it to something tactic like.
The point system for the girls can use a bit of help too, It's not that easy to get the right trait to get X girl. In my original run I got the kiss and the holding hands with Lauren, then I replayed to see other options and I fucked up things with a couple of girls. Maybe you can add a npcs roster with their bios and what traits they like.
Now, Penolope is another qt but :
Chloe > Penelope > Lauren - Redhead - Lauren sister >>>>>> Nora >>>>>>Aubrey >>Cheater
Thanks so much for your in depth feedback,
Love the idea of bios. I'll make the easy version a lot easier for the hotfix.
