Thanks for leaving this great feedback,
The Katrine dude is the old PC, because i will rework Katrine her content completely i left in the old scenes. In 0.06 the stats screen will show the character that is selected with their current weight gain stage. You can toggle off scenes in preferences if you don't enjoy these.
The coming Luna events will have her with glasses on :P
Idk if i want to make books free, i will have to think about it.
