Game has such a fantastic concept that I've gone looking for other similar games to see if anyone has made something a little more expansive. This works best as a demo for a bigger game...hopefully you're planning to do more! But as it is, the game is really really easy, because you basically win by not doing much. Drop coins, buy bows, upgrade everything steadily...never build more walls, never go far from the castle, just stay put and drop coins. Needs expansion, but with it, could be truly great!
