not a bad effort
Don't want to be over critical, generally I am pretty bored of these defense type games, but this is a pretty good twist on an old idea. Graphics are good and the game plays ok.
Seem to have found a bug though that stops me from playing again without reloading the flash, I ran out of ammo and died, then decided to play again, but everytime I pressed play it took me to the shop, I couldn't buy any upgrades for my castle or wizard, and pressing continue with game just took me back to the menu screen.
