We've updated the main branch with Comet Drop and a nicer light bakes and a fix for the jackpot extra balls.
On the beta branch we've added a multiplayer invite prompt which will show up on the left controller of the client. They have to select either Join or Ignore.
Please head over to the community forum to leave feedback on the steamworks features as we iron out the kinks.
We've also added a counter in the info panel of each game to show how many times you've played them so you can rejoice/despair about the amount of virtual coins you've spent!
Enjoy!
