What have I learned from this game? If you're going to wall-jump out of a chasm made of steel girders, make sure the tip of your ear is insulated from electric shock.
I really like this game and how it takes the whole "destroy the castle" concept and provides a less luck based firing method. Only minor complaint I have is that the levels were really easy; I got all golds in a little over 30 minutes without really having to think too much about how to finish them. It'd be nice to see how a sequel could up the difficulty level.
