Not having an update in a long time doesn't mean that Icstor has done any work during that time, which seems to be the case here since he was still pushing the release of 0.7 update in October for year 2020 before pulling the "version 1.0" stunt in December. So, to be able to release the "complete version" of the game as he claims to do, he would've needed to finish the content for 0.7 update and then also make all the content for 0.8, 0.9 and 1.0 updates in one month to be able to release it in February. Even if it would be half-assed, it just wouldn't be possible.
