It's entertaining, but too random to really promote strategy. And there is nothing to do but hit things with fireballs. It's not a bad game by miles, but Nerdook has done better in the past.
@ivot: Focus on hitting the scarabs. Buy the upgrades that improve the scarab coinage and spawn rate. Don't hit the cat-god, and try to use priests and soldiers to help yourself survive. I'm not sure if the nun-hat improves scarab spawn rate in level 7, but that's worth a shot as well. Good luck.
Fantastic
