Do you wonder where your keychain goes when you lose it?

In Master Keys, you take the role of lost keys trying to break into the basement of the building, in hope of becoming master keys. You fight giant padlocks and evil rusty keys, trying to break them into parts to create your own keys. Combine a key head with a key tail to create your own abilities, and add charms and key rings to your chain! Featuring a clever combat mechanic using marbles, and anticipated modular boss attacks!
