This was a compact but complex puzzle game, impressive for being written in 4 hours.
You are a ghost, only able to interact with the world once each year. The house you are in is being used for a vacation by guests. Your goal is to interact with them to guide them to the truth.
Unfortunately, you are very weak, and time is short. I found myself struggling (in character) to do almost anything, like opening windows and doors. But after replaying several times and exploring, I discovered the pattern needed to win.
Dialog and presentation were good and the puzzles were engaging and not too hard or too easy. Great work.
