Through whole playthrough of The Entropy Centre v.1.1.3 not even one achievement got unlocked. It seems like game supports achievement, but in some patch some bug must have been introduced that broke them. Highly unlikely it's something on my side, because I can unlock achievements in other GOG games that support achievements.

I don't expect it to be patched, as it seems it was developed by single person almost 2 years ago. Game is really good, definitely worth a buy without achievements, just thought people should know about this when buying the game.
