Great game! Addictive little gameplay loop. The risk-reward element is really nice. Though found it a bit easy to find a tower setup that took out all the minions and that I was also comfortable dodging, so the defending sections became too much waiting. But overall a very impressive package, with some nice visuals to boot.
(Do have to add though that game did crash once, right before I got 20k points, which I got a bit sad about)
