Hello,
This is a really good asset pack and I'd like to add it to my collection. But I try to use only Creative Commons or otherwise freely license assets.
"This asset pack can be used for any commercial and non-commercial projects and you may modify it in any way you choose."
This sounds great.
"This asset pack cannot be resold/redistributed, even if modified."
I have no plans (nor would I) of selling your assets, although I have a friend who is helping me make the game, and having the ability to redistribute the assets with him would be essential.
Could you consider a CC BY license?
