Having played through the first bit, I'm pretty impressed so far. I made a point of just trying to make all types of weird things I could imagine. I made Krakens and Hydras and Minotaurs... etc.

I was honestly afraid I wouldn't be creative enough to come up with new things to try, but trying to master each level I find myself being spontaneously inventive and finding crazy ways to accomplish things.

Even more fun is talking with my wife after she's done some of the same levels. There's a whole lot of, "Man I didn't even think of that!!" It's pretty awesome. Definitely gonna buy it when it comes out.
