Well, not really. It's true that the game has been more updated than the version that has been released on itch.io (On Patreon they have the 1.5 version). But it's from the 19/09/2023. The updates you see after are for a new game called "exchange" that he has been working on since bangxbang has stopped being updated. So if you buy the Patreon, don't be surprised that bangxbang has not been updated since more than a year.
