Observo is a short third-person survival horror game styled after early-2000s game classics, with a focus on atmosphere, puzzle-solving, and light combat.

You play as Edgar, a man who finds a roadside inn to spend the night in at the last minute. While the inn itself looks a little worse for wear, it has a friendly manager, clean sheets, and warm water, so he doesn't think much of it. However, when strange things start happening around him and Edgar suddenly finds himself in danger, his next objective then becomes escaping from that place.
