I love the theme! Playing as BBEG is always fun. Also theme implementation is really cleaver (5 stars no doubt) and background art is just beautiful. Gameplay is a little lacking, balance is really important in such games. To many recipes need food and gems are almost useless. I did not managed to unlock Reaper, more things were more important. I was able to stop enemies in 2 week and then just pushed them back. There were no feeling of incoming doom (other then my evil plan buahahaha).
I really had fun playing this, but there are some design parts that doesn't work.
PS. Now I want to make my own version of this game :D
