I loved this game! I particularly like Nikolai, not because he's mean, but because he has so much depth to his character and it's pretty easy to tell that he's subject to growth. He's really interesting as a character and I'd love to see more.
I also really like the protagonist's reactions because I think some games tend to overdo reactions to the point where it's more out of place than anything. Anyway! Great job on this game and I'm excited to play more! =)
