A: Hi genifah!
1. Yes, you are allowed to use our 3D icons as part of your game. This falls under our commercial license (you get it by buying the deal here).
2. No, this isn't allowed - it would be considered reselling. Redistributing the product on its own is not allowed, it must be part of a product where the icon itself is not the main value.
Hope this helps! If you have additional questions or are interested in a resell license, please reach out to contact@flat-icons.com
