Since I noticed that the forum is pretty new and empty, I decided that I should at least help those who are in need of some art for their games
Now, I did not make any of these, but when I am making dungeon-type rpgs, I find this website to be quite helpful!
Go to the "tile library" tab for all the pixel art. It is all under the "Creative Commons License" so you should be able to use that art as long as you give credit to the author.
Another website that might help is this one
I know it's not much, but it's something
And not all games made with Solarus should be Zelda clones either!
