Hey there i want to know how itch processes our files and would a installer be good,(so when you click run the main installer runs) And Would it break any Terms of service,I also want to know which is the best way to upload (Unity3d) games to itch?
This isn't about terms of service, it's about the app: no, please don't make an installer, simply zip up your game and upload the archive. And that's the way to go with Unity games, too.
