Hi,
you might notice 23 new achievements just popping in. Those can only be unlocked using the beta branch as I'm testing it before making it available by default. You can also use the beta branch to try out, but it will be live next week by default. While testing I found a bug that made some achievements not unlockable, so I made the fix available with all the achievements. All 23 achievements are available!
After this new set of achievements, all games will have at least 1 achievement. I will keep adding more from time to time! Ideas for achievements are always welcome.
