By the way, to add multiple platforms you need to name your .zip folders differently otherwise itch.io will think you want to replace the other one with the one you just uploaded. Figured that out after only being able to upload a windows version of my game and not have more than one supported platform, well then I changed the names of the .zip files so that they would be different and fuala! I had Mac linux and windows support for my game. XD mentioned this cause I noticed you only had linux for this game and I thought you might be having the same issue I had.
