I found an easy way to make gold what you do is at the beginning you kill baby beetles and snakes and get hides and shells and you take three of the shells and three of the hides to make the beetle shield the first shield you get a recipe for but if you sell it at the shop you get 60 gold for it while just selling the materials will only get you 30 gold + this if it helped you out
Terrific love it would love it alot more if it had more guns but upgraded machine gun is like a mini-gun so I am not complaining one gun that would be nice is a rocket launcher.
