There’s a Devil Woman? Really? That’s what KST came up with? I know, how about another female student at the school? There’s 2 guys, a teacher and a cheerleader. How about adding another cheerleader? Every location has a maximum of 2 characters (except home). The teacher’s house seems like an underused location.
The stepdad coming home adds to the grind. If the Dev wants an In Tee Are scenario with dad, then do it. Otherwise drop his character. This game has potential but the Dev can’t figure out how to move forward. A replay system and a useable save option would be a good start.
PS: how about continuing scenes that don’t go anywhere. Like having coffee with the stepsister? Not oh, I drank it all. End Scene.
