Can I update the game directly or do I have to download it all over again? Because if I have to download this all over again I might have to abandon this completely seeing as I no longer have the means to download this the first time I did
Hey ASW!
When updating to a new version here on Itch, you'll need to download the full game. (Either from here or through the Itch client/launcher). Saves do carry over automatically.
If you've previously purchased the game, press "Download" and there should be an option at the bottom "I've already purchased" and it'll take you to the appropriate page for getting the latest version.
However, over on our Patreon we offer a "Patch" system that will take you from X version to X. For instance, here's the latest free version. You'll see the "PATCH from X". If you are using patches, you can only update High res patch for the high res game, and compressed for compressed, you can't mix and match.

If however, you are several patches behind and somehow the patch system doesn't work, you're better off just grabbing a fresh, full download.
Hope this answers your question and helps out!
