Hey hey hey, it's tutorial guy again! Remember me? No?....wow, that hurts. Anyways, I'm here to give you the low down on the score counter. You see that (-1) there? That means you got one wrong guess. Every time you guess ???'s identity wrong, the counter increases. If you guess wrong 7 times (there were eight survivors, mind you), then you will receive the bad ending. There are 4 possible endings, so try to keep the counter to a minimum if you want the best ending! For reference, here's all the survivors of the last killing game
Syn
Czar
Toxic
Riko
Lilyian
Kaimine
Chopper
Black
...and good luck. I know you guys don't remember me and all, but I feel like you guys are the closest thing I have to friends...sigh, being a tutorial guy is tough...
