The AI will get better over time, may take a few generations. I suggest putting the learning_rate setting at 100 until the AI reaches a highscore of 150, then bring it down to 1. Highest score I got was 525 on generation 64. Overall I'm happy with this system, I'm planning to adapt it to other scratch games.
