Well I think there was much you could miss based on poor timing or anything. Also I think the slave route resulted overall in a bad ending but I can't be sure.
I hope the dev actively develops from time to time and might consider adding a walktrough again.
I hate the idea of already running into a game over depending on what route I want to try.
edit: I might have said that somewhere already, but I really don't like their lips being drawn the way they are here in some of the scenes.
Something in the face could be better and I suppose that might be it. Nice game otherwise, even if I'm only at known points till now.
