I have a theory why Kevin's path doesn't work:
I think Kevin's route is complete, but there is an error on day 17 that prevents us from seeing the other scenes. Before going to the camp you have to enter one of the bathrooms where Kevin is supposed to be, but when you click on it, a pop-up window appears that says the name "Kevin route is not defined" or something like that.
This message:
[code]
I'm sorry, but an uncaught exception occurred.
While running game code:
File "game/day17.rpy", line 181, in <module>
NameError: name 'kevin_d17' is not defined

I think that the other scenes are not unlocked by that scene, does someone not think the same?
