As I implied with "proof of concept", the purpose was to see if it works at all, not to make a game. It made mistakes and autonomously fixed them. Just a few months before, agents weren't able to do this. Now they're able to reach the goals you set, as long as they're definite, you're not making immovable objects collide with unstoppable forces, and the search space is not very diverse.
