The Astronomer's Star Chart

Professor Ilsabet Vane predicted a comet no one else could see — then vanished from her locked observatory, leaving star charts that are beautiful, meticulous, and deliberately sabotaged. Correct the sky, and the wrongness spells a message with southern coordinates and a March deadline. A two-screen observatory puzzle game you play in any browser — no download, no account. A branching investigation: the rival's letter, the unread application and her private journal decide whether you can follow her — and which of six endings the night gets.
