Really great game! It feels very complete, and I especially loved the incomplete information caused by the illness and the heirs turning into monsters. It fits the "Trust No One" theme really well!
Though with so little reliable information, I naturally chose... the person I would normally trust based on their relationship to me (no spoilers XD). Maybe having three people with equally strong reasons to inherit, like three children fighting over the inheritance, could make the choice even harder!
The music fits really well and the art is super cute too. I really enjoyed it! :D
