The dev is working on stuff, and posted a video of what's changed in some comments below, which it has changed drastically. The dev is basically creating a whole new game at this point, so I would hold off on purchasing until he releases update #5. It looks promising, and they said it was close to release, but it's been that way for a little while now. To answer your other question, no, it has not received an update since 05 Sept. of 2024.
