I tried this and really liked the demo so I paid. Unfortunately, I have not, after two days, received a password to unlock the demo. That wouldn't be too bad except that this game has the most annoying nag I've ever seen -- you can't quit this game when it presents you with its nag page - you have to Force Quit! The only actions it will undertake are the buttons on the nag page, and I've already been there done that. A major nuisance. Hopefully the authors will get their act together soon - if you want to do business, you have to be ready to do it.
