hello! are you asking me if you can make a game with this assets and sell it? because if that's the case, i'm sorry but no. the license these assets are under is, as indicated at the bottom of the description, one that allows you to use, share and edit them as long as you're not reselling it. Now, if you want to print them, do something with them and then sell the result between you and your friends, i cannot interevene and you can do as you wish, as long as it's not a public thing.
if you're asking me to make a game....eee, i'm sorry, but i don't have the time. these i made as an exercise, but i'm occupied with other stuff as of now.
UPDATE: you can do whatever you want with these assets, i updated the license.
