Email subject:Desktop Publishing — Steam, itch.io, and Cross-Platform Builds
Topics Covered
- •Unity build targets: switch platforms in Build Settings. Windows (StandaloneWindows64), Mac (StandaloneOSX), Linux (StandaloneLinux64), WebGL
- •Steam: largest PC game store. $100 one-time submission fee. Minimum 2-week review. Steamworks SDK for achievements, cloud saves, leaderboards.
- •itch.io: indie-first, no submission fee, instant publishing, smaller audience. Great for early builds, demos, and jam games.
- •WebGL: play in browser, no install. Lower performance ceiling but easy to share. Great for demos.
- •Mac code signing: you'll need Apple Developer account ($149/yr) and Xcode to notarise Mac builds for distribution outside App Store
- •Cross-platform differences: file paths (Windows vs Mac), input (controller vs keyboard), display scaling
