Wow, I can't believe you built all that in nine days!! I love the setup of taking control of dead enemies, and of controlling one big bad boss when the heroes get past your front line. There was a ton of juice and I came away understanding basically all the mechanics.
My only complaint is that the gameplay stalled out a little in the last fight. It was down to one thrall vs. the queen. Each turn, I could do a tiny bit of damage, and then put her to sleep. So I did that about a dozen times to beat the game :P
