by looking at nature of these games 1.0 will mean nothing really, it will be still unfinished game with many things that could still be improved and reason that we didn't got update is the fact that he was working on different game meanwhile and Raliv is currently rushing this game to jump to next project, that's pretty much it.
let's hope this game will get some more content later on at least but I seen similar thing happen with KoboldKare, the game was abandoned as soon as the developer started new project and after that nothing really changed in that game, no more new content sadly.
