Wasn't PN shut down for a night because of the leaks? And of course you can't actually beat the second level. It's an old PN build. Why do you want the emeralds anyway? If my assumption is correct, they probably didn't program Super Sonic in until he was officially announced. Because of that, the emeralds will basically play like Sonic 1: They ONLY get you a good ending. True, it is fun to play a game that is incomplete, but it's mostly pointless. And until Sonic 4 is officially released, all you can really do is mess around in it. If someone wants to see footage of the PN build, they have to wait for the game's release. If the second level's hell though, imagine the rest of the game. Probably tons of incomplete sectors and platform placement, tons of unaccessible locations and stuff.
