Hi! How would I update old games from you (I always have trouble updating on itchio), and what games have been affected?
you can update by downloading the game from the game page. don't know what games you've downloaded games previously, but you can check the version number on the page of the game you want to update to see if it's higher than the version of the game version you have downloaded. (i believe if you are using the itch.io app, it should make it clear if the version you have downloaded is not the newest version.)
