its simpler than youd think
There's the problem: I cannot think).
I'm so thank you for helping. Game was very interesting. Yes, some events was hard for dumb players (like me), but still it was very cool. I have only 2 complaint: 1. There's no "load" button in character's menu, what sometimes is a little bit annoying. 2. "esc" not working after you begin/complete endings.
Anyway it's a very goodgame.
