Caligo is a short, first-person exploration game. Sure, you can call it a walking simulator if you like. You have a fairly slow-paced walk, no run, and a crouch that I don’t believe I used even once. You explore various environments, while listening to a story being told: starting off in a lighthouse, you work through your way through a gorgeous forest, to a shipwreck, to a couple of more locations, all while trying to figure out why you’re here and how you got there.
The extent of your interaction with the world is to pick up drawings you find scattered throughout the various areas. There are twenty in total, and collecting all of them earns you an achievement, but that’s about it. Otherwise, you walk around and explore. If it were an ugly game, this would be an issue, but Caligo is presented nice and darkly, with lots of creepy decor mixed in with happy and fun decor.
