Me and my friend are making a game on separate computers. I have a Windows computer and he has a Mac. Our problem right now is how to find a way to easily export the tilesets my friend made from his computer to mine. Is there an easier way other than saving each file individually with Pencyl? P.S. My friend is not very computer-literate, so if the instructions are too complicated, he might get lost. Simple instructions, please, and thanks in advance!
