I've always wanted to play/make a game with randomized controls, I like the premise of it switching every 5 seconds.
However, as everyone else has said, the UI is a bit unintuitive. I would just get rid of the words from the display and use the arrows to represent the keys as opposed to the direction, i.e. If pressing up makes you go right, show the up arrow in the right slot. If pressing left makes you jump, show the left arrow in the upper slot. That way you can always look at the same place every time to see what key will let you, say, move right, as opposed to having to search the three slots to find the one with the right arrow.
