Secrets of Raetikon is part platformer, part flight simulator, part Metroid-vania, part creation myth. It’s a lot of things without ever settling on what it wants to be most. Really that’s its strongest quality. It just sort of gracefully floats along boundaries. Secrets of Raetikon points to the value of exploration as an end in itself. The whole game is deliberately cryptic, even the name emphasizes secrets (and something unpronounceable). The appeal, though, isn’t in uncovering the game’s secrets, rather it is in being a part of them.
The opening title shows a colourful, humanoid bird plummeting through the sky and crashing into the earth. Immediately, the player takes control of said bird and learns the ins and outs of flying, collecting crystals, and installing them into a giant machine. Secrets doesn’t waste verbiage on anything that isn’t necessary to exploring the game, the impetus is to just explore.
