I added a "License" part down the description. Here it is: "You may use these assets in personal or commercial projects. You may modify these assets to suit your needs. You can NOT re-distribute the file, no matter how much you modify it you can use it but not share or re-sell it." So the answer is yes! Thank you for your interest!
I'm developping small games for micro controllers with very few ROM (8kb for code and data) and would like to ask if your license permits to include a few of the tiles in source code form (as hexdumps in a C source code). The whole project is to be released under GPL v3.
