Hey there, I'm honestly very interested in your pixel art, but I honestly can't use them with the license you currently have it under. As I understand it, if I wanted to use these assets in a commercial game, or any kind of game really, its a grey area that the source code for said game must also be distributed in a similar way due to the share alike license, and the wording of said license (which honestly sucks but it can indeed be interpreted that way, so many people avoid CC-BY-SA assets for serious projects, since they want to keep their source code).
Do you have any intention of possibly selling your assets under a different license, like CC0, even if you charge a bit more for it? Or maybe you can sell some of this asset in a separate CC0 licensed bundle?

Since there seems to be some confusion, I hope you don't mind me chiming in.
LimeZu is selling the assets under the CC-BY license, which allows you to use the assets (for either free or commercial projects) as long as you credit them.
The license you're talking about is CC-BY-SA, which also allows you to use the assets for your projects as long as they're credited. BUT there is another term added called ShareAlike, which means you need to distribute your creation/product under the same license. This is what you mean by sharing the source code right?
In summary, LimeZu's assets are under CC-BY, not CC-BY-SA, so you don't need to share your code :)
