Naina

Roshni and her sister, Naina, haven't seen each other in years, but when an ominous note shows up in Roshni's mailbox one day, she ends up on a hunt that could lead her to a person she doesn't recognize anymore.

Started 5 years ago as part of a game jam with friends, then discarded as incomplete until recently, when it was finally sealed up and given some form of closure.
