Overall, very good!
I understand that this is only an experiment. For an experiment, this is exceptional! For an actual game, this is still very good. The only thing I would comment on would be the amount of gold per monster and the fact that Dragons are a bit too powerful. It seems as though the only way to kill a dragon is if you get Divine Edge or you get lucky and Dragon hits low. On one run, I encountered a Dragon but I wasn't even presented the opportunity to purchase Divine Edge! A question that I have is: "What are the golden tickets for?". Overall, very good!
