I recommend using the itch.io app, it allows you to update games without having to re-download the entire thing and usually only takes a minute or two. This only works for games that are hosted on compatible sites (mainly games uploaded here.)
Can you please give me the link to the itch.io app, for Android
That unfortunately doesn’t include this game 😅 at least the most recent release was uploaded to Mega, which is not supported by the Itch client.
