About Master Key
Master Key is about exploring a dense world, fighting enemies and solving puzzles to find out what an old, rusty key discovered deep in a cave can open. You find your own path through the world: nothing is gated by the story, and the game does not guide you by the hand.
Explore the world
Item-based exploration leads you through dungeons and toward shops, weapons, powerups and secrets. The game includes dozens of enemies and between 5 and 20 hours of content.
