How can I earn Struckd Coins?
You need a monetization method in your game. The simplest way is to create a game and add a premium item (highlighted by the little diamond icon in the asset preview) such as Fantasy Axe. To find more assets that can be used to earn coins, open the assets library and find the "Earn Coins" category.
Another option to earn coins is to add a coins requirement for the exchange system or doors open requirement.
