So... how does Co op work if you don't have controllers and you're using a laptop? You said no online games, so if I want to play with the hubby, are we have to have to sit wedged up against each other shoulder to shoulder duel welding the keyboard?

you will need to buy a gamepad, they arent that costly and if you are playing games on steam its probably a good idea to own one. (spelunky + super meat boy alone shoudl make it worth it)
