Even Steam couldn't handle too much attention to the patch 1.1 for Collect All These Stones (CATS) and had been down for a while
Now, it's up and running and you can enjoy the game!
Patch notes:
Fixed leaderboard score registration
Added finish screen with statistics
Fixed current random seed display in escape menu. Random seed for restart game is generated correctly now. Current seed is a read only text field now, so it can be easily copied
Added two more achievements
The game stays active in background now
