Hi Steam!
We've been in early access for a little under 6 months. Trust me - that was not the original plan. We have been working hard to bring you online multiplayer in Spinball, but until that day comes, we have added an extra arena and made some other tweaks and adjustments. We're currently alpha testing the online mode and once we're ready to start beta testing, we will make a beta build available here for all of you to try it out!
Thanks!
