I played whole game over the last build 7.45 and I didn't get any achievement. Still they are not working at all. I don´t actually care about achievements but I want to leave my feedback about this topic.

And what a beautiful and magical game :).

Just started the game and didn't get any achievements, yet. I guess the "Unbound" should unlock very early in the game, but didn't for me.

edit: I'm on build 7.45

Unfortunately still true for me. Version 7.45 too, I hope to see this fixed soon.

"The Pinnacle
Reach the highest point in the highest tower."

Nothing unlocked for me. I'm on build 7.45.

Steam version got updated to build 7.91 yesterday. Maybe if this hits GOG in a few days the achievements will be fixed.

Edit: Very good news everybody, 7.91 is available through GOG Galaxy auto-update and the achievements are working!!! Just tried with the very first one by starting a new game and it popped up immediately.

I can also confirm on build 7.91 that achievements appear to be functioning again. After I loaded into the game the achievement for collecting 55 mushrooms popped and when I tested out the one for reaching the highest point in the game that unlocked as well. Thanks!

Edit: Finished the game. Everything appeared to unlock properly besides the achievements for defeating all the spiders and completing all Gusto and Fatale side-quests.

New update 7.91 is not availabe on GOG as a offline game download yet.

EDIT: Well, now it is :)
