Interesting take on the theme! - I tried a couple of time to pass the first lock, but wasn't able to do it. I understood that the password was 52 but somehow it did not work :s.
It feels that the game is a bit ambitious for a game jam, maybe by reducing the amount of control buttons the game can become simpler? - I am not an expert game developer, but something that I have learn from all the gamejams that I have participated, is that it is better to keep things simple for the player to understand the mechanic quickly thus spending more time on the content of the game.
Good submission nevertheless, and good luck in the Jam :)
