I would love it if you would make a clear license file.  For example, am I allowed to use these in my games?  Perhaps you intended them for personal or non commercial projects only?  I might assume since that you are releasing them to the world and asking donations that you are intending them for any use, but I am not sure I can assume that legally.  A license file clearly indicating what rights are granted would clear this all up.

Thank you!  Teşeküller!

Of course you can use them in all your projects. Commercial and non-commercial. I will update the file. Thank you for the feedback! :)
