What does the corruption stat represent in this game?
The corruption stat represents getting 'cucked' by other guys on campus. It is not related to a girlfriend/fucktoy balance but rather indicates that you lose out when another character gains favor with a girl you are interested in.
What happens if I don't seek out a particular girl?
If you do not seek out a specific girl, the other guys on campus may still target her. Once she hooks up with another guy, it is 'game over' for that girl in terms of pursuing her affection.
Is there a way to access the bus stop once a certain flag is unlocked?
It seems that unlocking a specific flag does not actually grant access to the bus stop. There may be additional requirements or issues with accessing it.
Are image folder names case sensitive in the game?
Yes, the image folder names are case-sensitive. Normal images use lowercase while bubble images require uppercase naming. A workaround is to copy the whole image folder and create a second one named 'Images'.
