I played a few times and won the last couple. :) I didn't realize at first that the right mouse button was to move as well as attack, but that was probably just an oversight on my part.
The atmosphere was cool! I liked the use of greens and blues to make that spooky graveyard kind of vibe. The models did look a little sharp for a Sokpop game? But honestly, I don't know the first thing about getting their aesthetic -- pixel shaders? low polygon counts? -- so kudos for what you did end up releasing.
If I have one major criticism, it's that I wanted a little more visual feedback from my inputs. I couldn't always tell if my instructions who to target were being received, and when my units had orders to follow vs. waiting for input.
