hey GoodBunny thank you very much ^^, then with all rights reserved license the people who purchase will be able to use it in their games without problem?
if thats so then you solved my doubt =D I appreciate your help
“All rights reserved” means as it says: that you reserve all rights to your work. It’s the closest thing in the list, and one that is strictly a superset of what you want, which is very important.
There's no way to give developers just the permission you're talking about using the itch.io dropdown selection box. You'll have to write the permission in words yourself. If it's very important to you, you might need to consult a lawyer to get it right.
