Day 1 patch notes, and thanks!

Hey everyone,

Wow. What a fun launch, thanks to all of you for picking it up and taking it for a spin. The great news is that our QA process pre-launch seems to have been watertight, with very few reporting bugs despite lots going through..

That said, you found a couple of typos, so we've fixed those... please report any other issues in the pinned dev thread on the game's forum.

Thanks so much for the support, keep those steam reviews coming, they really help our metrics, and tell your friends!

“Quarantine Circular is another brilliantly written game that will have you taking up different mind sets to get through it. It's at times charming, upsetting and inspiring and will have you playing it through to its conclusion in one sitting without you realising.”
10/10 – The Digital Fix

“If you like stories, characters, dialogue and moral choices, it’s worth one playthrough — or maybe even six.”

“Quarantine Circular is, much like its predecessor a short playthrough but has multiple branches that the story can go down, so one playthrough is not enough. It is a beautifully crafted game and ... is well worth every cent. It presents a compelling scenario for thought, infectious to the last moment.”
9/10 – Gamespace

  • Art Gallery showcasing the development of this new story.

If this game is ‘short’, what’s to stop me getting a refund when I’m done?

We’re so grateful to the community for the low rate of refunds on our previous short, Subsurface Circular. We hope Quarantine will earn the same. Our games are made by a team of hardworking people, and it’s encouraging that the Steam community consistently shows respect for this passion and effort.

Do I need to have played Subsurface Circular or other Bithell games to enjoy this one?

No. Quarantine Circular tells its own self contained story.

Plague? Adult? Is this game going to ruin my lunch?

Nope. Quarantine Circular is about on a par with the average network TV science fiction episode in its depiction of mature themes and gore. We like to think of it as ‘adult’ in the sense that it focuses on themes of humanity and philosophy, not because of any grossness or sexiness.

Of course, there’s nothing sexier than a good sci-fi short ;)
