Pretty cool. I love this sort of game. My first pyweek entry was a fire emblem clone: http://www.spinheaddev.com/downloads/mechrev.zip
Several things brought it down though. The interface had too much clicking, the strategy was unsound, and my a* was much too slow. Take a look at the source if you like, maybe you can find something useful in there. Although I doubt it. One of the best games I've made, and probably some of the worst code I've seen in my life :) Your tactics demo seems pretty hard to win, have to make better use of those healers I guess!
