As this is an extremely render-and-animation heavy game, I made the choice at the start of development to render everything out at 720p in order to keep the filesize as small as possible (and even still, it's over a GB already). My next game will use a system that will reduce bloat considerably, so that will likely have QHD or higher quality renders. For now, though, I'm afraid CK will have to stay at 720p.
Gwen's Yandere mode currently has three stages:
1. An incident at the Manor's front door.
2. She starts sending you texts during the day.
3a. Her texts get a little more... intense.
3b. An incident occurs at night which unlocks one of her Quirks.
That's it for now, but a lot more content is planned for her :)
