After trying out the electrical powers on the mannequins, you're supposed to go to the edge of the roof and jump off by pressing the x button. I keep going over to the edge, pushing the POI triangle button, and then pressing x, but nothing happens. I figured maybe it was glitching, so I restarted the game and tried it again. Same thing- I pushed x, and nothing happened. I'm extremely frustrated by the whole ordeal; I've never gotten stuck on the first level of a game before.
Is there some kind of a trick to this, or did I get a broken copy of the game? It says to push x, which has to be the simplest task on Earth. So, I push x. Nothing happens. I have no idea what I can possibly be doing wrong. Help please!
