Use the "Game editor" section at the bottom of each game page instead of this editing page. It is much easier to make your game work.
To create the game map here, make a grid of
x is an obstacle,
. is a position the character can go,
i is the square one,
o is where you have to go to finish the game (several arrivals are allowed),
b is a bomb.
Only type those five characters! Do not put empty lines. Each line should have the same length. Remember Tux the penguin can go on the left and the right, can jump up to 5 squares and is two squares high. He can't move outside of the game map.
