can you get all 12 cgs in the demo?
No, sorry for the confusion, there are a few place holders.
There's going to be 5 pics unlocked by Masturbating as each character, 5 pics for getting raped as each character, 1 for unlocking Snow, and another for unlocking the fifth character. The blank ones are just to keep the order right.
If you have 6, you got all the possible Polaroids in the current demo. (1 of Snow masturbating, 4 of each character being raped, and 1 of Snow unlock)
