It's kinda sad that (according to the Store page features) Steam has BOTH Cloud Saving features + Achievements; meanwhile the only ""feature"" available for GOG players is a measly:

"Single-Player"
(EDIT: The store page description of the game even mention achievements even though there's none on GOG.)

I don't want to be pushy, but please either update the store if i'm wrong, or instead add Cloud Saving and/or Achievements on GOG as well. It ain't fair to pay MORE for the GOG version (alas, the game is straight up more expensive here on GOG in comparison to Steam where I live) whilst simultaneously having less features. It's a bummer.
