Great Game! Why no Patreon link? can't wait for the next part
Unless the author wants to be universally hated by every artist he puts into the game plus their fans, it's better to avoid any type of funding.
You simply can't take animations from others artists, put it into your game and ask people to pay you.
They always catch up and they will take down the entire project.
Which will have patreon block both your account, possibly IP and your bank account/paypal.
Rightfully so. It's a pretty serious matter.
It's not worth it at all.
If anything, there's plenty of Blender tutorials out there.
If developer wants, he can cut the weak link of the project - animations of others and instead shift to images made from his own renders. Takes time but it also makes the game way more personalized.
