I loved the sense of atmosphere here! There's something really cool about games that explore a really short timespan or sequence of events. The fairly light ruleset and limited turns both work in the game's favour, with the former directing the player's focus naturally to the secret-sharing mechanic and the latter providing ever-increasing tension and a "deadline" to play in the face of. The fact that the players cannot “win”, but that this is not explicitly stated anywhere but deducible from the mechanics in play, works well too.
The (kind-of) unwinnability and the way tension naturally increases both reminded me of Ten Candles, but this definitely feels like its own game. In particular, the secret-sharing mechanic makes the game feel less like a puzzle to be solved and more like a brief moment of intimacy between the characters and a meditation on death for the players. The mechanics that are there prevent the game from feeling too freeform, and give an extra layer of tension in holding off the threat long enough to explore the characters' secrets fully. I think this would be a really enjoyable (if sad!) game to play with the right people. Thanks for submitting!
