So um...I have no idea what I'm supposed to do. I mean, like at the very start. I get out of my chamber pod, walk through the portal, enter the first room. Step on the switch, a cube falls out. Am I supposed to have a portal gun yet or what? I'm so confused. EDIT: Oh, I was supposed to walk up to the cube and push E and then it kind of hovers in front of me. Why didn't I think of that.
