@1corn2 Dont worry, your customers will stay indefenitly in the shop, so if you are out of stock, you'll only get customers till your shop has reached his customers capacity and you can craft in peace
While this game is extremly similar to sword and potions 2, it's still better then it on certain points, like for example quality, price negocations, and less waiting in the city. Also, graphics are a nice change.
Planet Shield isn't OP, it's annoying for other players but the guy who protects himself cn't attack either. BUT the planet shield II is really one overpowered weapon, since he's blocking 3 attacks, and still can attack. The only way to counter this are multishot weapons, or the minigun.
