First things first- for some reason it took me five restarts before I got this game running. Each time it crashed the first time I selected the demon. The last time though, it worked! And I liked it! Short and minimalist, but nicely done.
I honestly don't know if using AI is cool. Is this innovation, or cheating? Meh, I used AI today to write some sql queries, so to innovation it goes :)
Good job!
