Nice roadmap posted on some other platform where the game is released.
I bought this yesterday cause it looks so good, and is so very farily priced, but I will wait a while before playing and let some of these be implemented first :)
I have LOADS in my backlog so no hurry, and also it's summer now :D

Vsync ✔️
Resolution selector
Decoration details slider (separation from quality setting)
Change default bind of the Hint Button on PC (it's TAB now, that's silly of me!)
Custom keybinds
Mute (or pause) game when it's in the background
Some adjustable feature that improves grid and height readability
1st Content Update (more levels, music, animations, level themes etc.)

Sounds good, and hope you'll sort it out with the GOG-issue :)
We sure want all those updates in here too, for offline-installers as well as those using Galaxy :)

Are there achievements on the GOG version? Thew are advertised in the shop page but does not seem to listed on GOG Galaxy, so just wondering if it is better to wait some days before beginning the game. :)

Seems everything is working though, it's just that the achievements are listed only when the are unlocked, thus always showing a completion rate of 100% from the first unlocked. :)

Could you please set the achievements to production mode? That's why they're invisible at the moment. ;)

You're welcome!
Great game btw. - I already unlocked four achievements. :)

I'll try my best! :)

For the moment (only 50% through), It's the type of challenge I love: the one where you can pretty fast reduce the number of possibilites and iterate on the very small remaining ones. I assume it becomes insanely hard later, but by now the feeling while playing is perfect as a Golf Peaks or A Good Snowman Is Hard To Build. And absolutely beautiful. Well done!
