Portal takes the form of an experiment and you soon find out that at the end of the 19 levels there is a delicious reward –
a cake! Although there are small problems in getting across rooms, as you progress things get more complicated and along
with portals there are energy balls we saw in Half-Life 2: Episode One, that cannot be captured for transportation, but can
be directed using portals towards special locations that use their energy. We also deal with large buttons which open doors, once a weight is placed on them – this is where the companion cube comes into play, which that can be moved around using the portal gun.
