Yeah, agreed. I can only hope that they're trying to raise funds for some sort of hard times they've fallen on. I don't want to imagine that these devs are greedy people.
Is this "1.3.0" update the public Itch version, or is it one of the substar-exclusive versions? Because the most recent update on Itch says it adds "new achievements", and the public Pool update doesn't mention achievements, so I'd assume it's the substar version.
Either way, this update naming scheme is unclear. Why not name the updates like the dev does on Itch, with the update date?
