The beta had around 5 pre-made levels, only the first three were tutorial levels. There was a creation mode which had a fraction of the tool kit that is in the full game (which means the levels you've seen so far are only utilizing a small amount of the tools on offer in the full game which is pretty impressive). There was also online where you could mess around in other peoples levels with 4 other people. That was probably the most fun I had in the beta. And Kentarou was right, there is a pretty cool intro as well.
