Actually, he did share assets, I cant remember exactly, was it here or at fan assets thread, but it's easy to find, just filter out his posts... It's hard work of course, but not as hard as building it from start. Anyway, I was not advocating somebody to take the game over, just commenting.
I hope he will release an update by the end of year too. Biggest problem would be coding, he tried to make very complex game (not as gameplay, it's actually easy to play this, I am speaking about code structure), and he made a lot of mistakes. I am not criticizing him, it was ambitious from him, and I hope he learned a lot for possible future games, just game is the mess when it comes to code.
