A cool game concept and the visuals were pretty cool.
I did find that it was pretty hard to register if you were making any progress with the game overall so maybe some fine tuning to let the player know what they did right or wrong.
It felt very much like the tumble;rs of a safe and as such i kind of felt like it was a sequential thing which didn't seem to be the case.
A very intriguing idea which i would love to see worked on. I will definitely play any future versions of this!
