To boot up the game multi click the flag. For the first mini game you use the number keys. Then when it really begins you use the up and down arrow keys to move forward and backward. (Though you should only want to move backward IDK why I coded a step forward.) After the minigame ends, you'll notice the numbers in the corner labeled "Stamina" and "Distance From Exit". As you walk, you use up stamina. If you don't have any stamina, you can't walk. You recharge your stamina by staying still. You need to reach the exit (which is the distance from exit) in order to win!
I thought theirs was to hard and frustrating so I made a version so you pretty much always wins
