A good effort.
I've played others like this, but new ones are always appreciated. Also one can see that you (collective) have put a lot into this; I would hate to see it get downrated just because of simple bugs.
I, like others, am experiencing the moving/not moving bug. I have the latest Internet Explorer and Flash, and I Know that it is not a problem with my comp. specs. I just finished cleaning my keyboard, for pico's sake!
Suggestions: Save feature-definately, arrow effects, i.e. fire dmg, poison, slower mvmt due to ice, etc. And yes, the inflation of the health potions really hurts the bank.
