Thank goodness this game only has a demo out for PC right now:

If it had a full version, after playing the demo, I would have had to buy it so I could keep playing. A little bit of a bummer that it only has twenty levels but I suppose that it might get a bit more involved outside of the demo levels. The smoothness and obviousness of some of the concepts really let me get in there and play it. Being more involved in a tower defense games is a good time.
Ars has a review of it as well

I’ll be watching for this one on sale, that’s for sure…
