Loved it, excellent use of theme, very fun character. I _think_ I understood the 3rd puzzle, but man is it hard to do math quickly while the timer is going. I couldn't keep up once I got to 4 - I am after all a mere mortal (now without a soul)
haha, yeah! I lost my soul at leas half a dozen time too XD
When I play tested for the fitst time I almost scratched the idea. It took me some tries to get used to doing the math. What helped me was choosing some key numbers and focusing on them.
