Thomas was Alone developer Mike Bithell has announced - and released - his next game: a follow-up to Subsurface Circular called Quarantine Circular.
Like Subsurface Circular, Quarantine Circular is a science fiction text adventure-style game that can be completed in a couple of hours and costs 4.79.
Unlike Subsurface Circular, however, Quarantine Circular includes multiple endings and multiple active characters. So, you can have a drastic effect on how the narrative goes and, according to Bithell, even who is present in the game's final moments.
