First of all, a big thanks for a beautiful game! Incredible atmosphere!
I want to report some glitches I've encountered so far, just in case it is helpful for the developers. I just didn't find any other way to report bugs (except for sending an e-mail - but if that's preferred, please let me know).
Now, it happened to me once that in the "piskvorky" game ("get 5 in a row"), I actually got 6 in a row (by placing the last stone in one of the middle positions), and it wasn't detected as winning. Screenshot: (click for full res)
Also, the game crashed once on me: when I got into the elevator, put some dirt on the floor, the cleaning robot came in, I picked him up and something fell out of him - that moment the game crashed with "Segmentation fault". However, after playing again from my last save, the situation went fine.
[I forgot to say: linux version.]
