About

JOIN THE DISCUSSION, DIAGNOSE HUMANITY
Amid a global pandemic, an unknown entity has come to Earth. A small group of humans now face a decision on behalf of their planet: Should they trust the stranger that arrived from the stars?
Quarantine Circular places the fate of a vulnerable human race in your hands. Your dialogue choices in conversation with your fellow humans and off-world visitor will determine how the game plays out, and how its story ends. Work with your team to figure out if your new alien acquaintance is here to help the human race, or whether they plan to strike while the planet is weakened.
This self-contained short story takes around two hours to complete and is split into several chapters. You can play the game in one sitting or, if you prefer, unfold the story in smaller pieces that can fit into a busier schedule.
Quarantine Circular is inspired by classic adventure games and modern dialogue systems, and developed by the award-winning team behind Thomas Was Alone, Volume, and Subsurface Circular. You do not need to have played Subsurface Circular in order to follow Quarantine Circular’s story (though if you enjoyed one, we think you’ll like the other).
Key FeaturesA polished, one-sitting game.
Social dynamics and greater choice enhance this twist on classic text-based adventures.

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.

bithell doing their thing
Yes.
A+ little visual novel. Game is short (3-4 hours at most), but the story is very interesting with some fun twists and turns. The characters are great, the writing is good, and the music is fantastic. Price point is quite good for a game of this length, so don't let the short length stop you from enjoying something special.
not as good as subsurface circular but it does expand on this world ALOT! i wish tehre were more games that would build out this world even more!
I was on the fence about Quarantine Circular. It tells a compelling story, but it feels lackluster and overly verbose. This game leaves me feeling like it could've been an email. I would play Subsurface Circular instead if you haven't picked it up.
Very engaging narrative science fiction. A interactive exchange between a ship's crew members and a massive crab alien. Absolutely worth the price of admission. Will checkout the dev commentary on a second playthrough sometime.
subsurface stuck with me much more than this one will but i think that the story was actually pretty dang intriguing and human in this one. i think what really shines through the most is gabriel as a character and as a symbol. it's for sure worth buying for the $3 as i spent. i'd say it's around a 6/10 compared to subsurface which i'd put closer to an 8/10, mainly because of the setting and narrative being a bit less unique and captivating in it's direction. it also lacks as much charm and style but the focus is the story anyways i suppose!
I cannot describe my seething hatred for Teng. gud game though
All the characters were one dimensional. Teng and Lisa were insufferable. Writing was subpar comparative to the predecessor "Subsurface Circular". Tempted to get a refund, but for $1.70, I can't really complain. Overall, a playable experience that left lacking greater in-depth writing and sense of urgency as every choice you made actually does not matter.
This visual novel felt like no other I had played. Despite its short length, it manages to build up a whole universe-as well as characters and organisations which all have different philosophies and motivations.
