Master Key

Master Key is an exploration game where you use items to explore a dense world, fight enemies, solve puzzles, and find your own path through dungeons and secrets.

An old rusty key is found deep in a cave. Explore a dense world, fight ferocious enemies, and solve puzzles in search of answers.

Features include item-based exploration, dozens of enemies, shops, weapons, powerups, dungeons, and lots of secrets. The game offers between 5 and 20 hours of content.

It does not hold the player by the hand and is described as a love letter to hiking and exploration. You have to find your own path, and nothing is story-gated. There is no language support.
