TLDR: If you want to sign up, here's a thread on our forums where you can do so.
Only a week left to go! This has been in many ways our largest project yet, and it's one of our favorites. Huge thanks to the more than 100 testers that have volunteered their time to help us refine it over the months.
We are still looking for fresh eyes to help us consistently refine the new-player experience and make that as seamless as possible, however. The less you know about the details of the game, the better -- for someone who thinks the idea sounds cool and wants to get in on the action, we want it to be as easy a process as possible.
We still have a backlog of around 27 testers that we are letting in 5-10ish or so a day at this point, but we can always use more, running up to release.
Thanks for your support of our work! It really means a ton to us.
