Great!
I'm actually pretty hyped for this game. It seems packed with content, with tools clever enough to make pretty much anything you want. Like t3mporary_126 said there's still a lot that could be added, but I wouldn't mind getting an expansion set for this game. I think it'll happen.
Can't wait to create some awesome things! I don't even know what style I'm going to use the most, at the very least I'll make a full 4 level world with each of them, and then we'll see after that. So excited .
