UnholyVision: Does this game have GOG Galaxy achievements and if not will it be getting them? Also, does or will the GOG copy have the leaderboard feature like Steam has the Stats feature?

I tend to buy both Steam and GOG based on features. As I feel I'm getting more for my money so to speak. The GOG game has Cloud and everything else but those two features listed, which is making the decision on which platform to buy on harder.
We're hoping to have achievement support added as soon as possible. Unfortunately, we ran into a technical issue delayed the game's achievement implementation.

As of right now, we don't have an ETA as to when the game will have achievement support added.
