Jump: Up
Blue P0rtal: ??

Played a flash game of portal...
Was not bad.
If you can do it have character shoot a bullet that turns into one or other portal on collision on a wall maybe... using a direction clicked perhaps for aiming the bullet...

Will have to take some special code to ensure it hits dead on a wall and not go off corners but I'd imagine would be best controls. =)
