Should of stated this in the other reply, but the pack is completely free to use. Even commercially in game projects, I just don't condone the use of my work in AI generators or people reselling the assets as their own.
But if you want to use them to make a game and then sell a game, go for it. That's what this resource is for. And I would seek no financial cut from you. But if you do make a dope game, I always appreciate the mention. And if anyone has found value in the pack and can throw me dollar or two that's awesome.
