Hi Steam,
First of all, the bad news - Spinball Online is unfortunately not going to happen. Our small team has been stretched thin and our lack of resources has finally caught up to us. Despite our efforts, we aren't going to be able to bring online multiplayer to Spinball.
However, we have decided that in lieu of that, we want to give you more content! The final release will have Challenge Mode, where you can test your skills in more than a dozen challenges! The final number is not yet determined, but it's likely that we will also open up modding so that you can create your own challenges as well :D
We will also most likely be adding a few more arenas, so please stay tuned! We are excited to finally remove the 'early access' tag from this game, and we look forward to that day very soon!
