This game is surprisingly complex for a 4-hour game. There's conversation (although only ASK X ABOUT COMET works in general), many locations, a vehicle, rope.
There are a lot of grisly details. As a content warning, this game has frequent references to suicide. That part was a bit too dark for me.
I only found one ending, on a cliff. I'm sure there are other endings (I think other reviewers have found them).
