Somebody should tell the dev that that's very confusing. Each update should be at least an additional +0.01 to the version number.
Exactly, I keep my stuff pretty well sorted (1 folder for each developer, with subfolders for each game, which may also have subfolders incase they split up a game in seperate episodes or seasons, etc.) But, I can't keep track of every update every day. So, occasionally have to check whether I got something just by comparing version numbers. But, when version numbers aren't used, well, I might miss an update. No matter if it's here or on Patreon for any of the games I support there. And no matter how small the fix, even if it's just a single typo, not updating the version number basically means: "I changed something, but it has no impact for the players, they won't see any difference with the previous version, and I might as well not have bothered updating at all."
