Ok well I bought portal a few days ago on steam, I've really enjoyed. But I im stumped on lvl 18 or stage 18 whatever you want to call it. But anyway I have got the energy ball in the thing that it goes in and the bridge thing has started but I dont know how to get to the top floor were the cube was I think I know how to do it but it dosent seem to work so you people who do play it I would be very pleased if you could give me some advice.
And the people who are stuck on other lvl's just say which one and im sure the people who look at this will help.
