I picked this up with a (perhaps wayward) recommendation that it was a good mystery/puzzle game to go alongside others I've been playing but it seems a lot more like a social engineering game where I'm trying to balance previous conversations so as to be able to even access evidence I need, while also be gated by the limited hours in the days the game gives me before running up against the chapter end.
The only suspect I wasn't able to thoroughly look into was Lucky. Of the other three, it seemed like a pretty weak conclusion to come to that they were the murderer, however since it took me over five hours to reach Act 2 I don't know if I should bother running through Act 1 again to try and get a more satisfying resolution.
