get the game, there's only ver 3 in itch io
ok the game isnt fully out yet so the version on here is the latest i think so if you wanted to figure out when the game updates (you also have to re download the game every time it updates) you will have to look at there patreon which you can find a link somewhere so thats all i can do to help if your trying to download it you may need to look up a guide sorry i couldnt help mutch.
