  • “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

  • “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
