I have no idea what you mean? Not sure what the "activate update" is for?
I need to search for it later, I think the feed told me it's an update and I got nothing showing me that I can do an update.
I am using the Itch.io app, so if there is an update out, then you might have forgotten to make it so the itch.io app (browser?) thing get's it too.
From what I remember I played it on itch.io app before
okay i didn't reat that it's just an progress report, but above it starts with
published an update15 hours ago.
