LBP Beta, I got in, here's my impressions:

Yeah, it's definitely worth the hype. There are 4 single player levels in the beta, two of them are tutorials, and one is a hidden level. The two tutorials are kinda slow, but they serve fine as to introduce you to the basics (grabbing, platforming). The third level is amazing, you have to grab to a windmill and let go in the exact moment so that you can reach the platform you are aiming for. And you also get to play with the jet pack (which is AWESOME).

Then... after you finish the three levels you might (or not) unlock the fourth one (based on your performance), but you unlock access to user created content!! I've played like 30 levels probably, most of them are kinda short but fun none-the-less, but I've played 4 levels that blew my mind:

1.- You have a cannon, and if u press a button you shoot a cannonball, so you gotta aim your cannon at a dragon (which shoots cannonballs at you, too) and try to kill him.

2.- A race to the end (designed for four players) using vehicles, I played it alone, but you gotta grab onto a vehicle (which looks like the really fast ground vehicles from "The return of the Jedi", I think they're called speeders or something like that), and they start going really fast.

3.- A simple level that was nothing but platforming love, you know, the basics: don't fall to the fire, jump the electricity, etc.

4.- A level that resembled Mario Bros. LVL 1. It was pretty identical (everyone knew this was bound to happen, lol).

So yeah, in short words, the game pwns.
