As I said in my post 3 months ago. Check the dates on the releases and then look at the file sizes. The latest date with the largest file size is the latest release. The v.10 you refer to SHOULD be the "Reworked" and Final Release of "The Guardian". The actual version number is V1.0.... Any version you find with the decimal before the numbers is an older released update which means they are not complete. IE: V0.12 was newer than V0.11 and of course any "Lower" number like V0.10. Always look at the date of release of that update AND the file size of each release. The larger will usually be the newer unless there is a note attached to the update about any change in file compression or rework of the game that reduced the download size. Usually this surrounds display file sizes or compression methods...
With all the various site political activities we see accross the net over AVN games and content in them some developers are harder to reach so keep an eye out for a note from the developer, including this game, for updates like changes of name or venue. IE; Seathblack, Blackheart, and of course the other sites that support AVN game developers. Some are pay to join and participate like Patreon etc.
Good luck from here.
