Updating through Itch.io

Hi, everyone. I was wondering how I would go about updating releasing a game and then updating it on a platform like Itch.io. Obviously, with mobile, we just push the new build to the app store and that’s the end of it but how would this work on itch?

Is the end user required to re-download the new version every time it gets updated or is there another system I could use?

The game has chapters, similar to Telltale’s adventure games and I’d rather not have the end users re-download gigabytes of files at the end of it.

You should go over to itch.io and read up on their patching system.

Within Unity, take a look at Asset Bundles.
