While I enjoy looking at my high scores, as an earlier comment mentioned there is a large degree of randomness involved in this. As I play more, I find myself intentionally being extremely reckless, as my goal is to maximize the chance of beating previous scores with no regard to chance of failure. This seems very counter to the theme of the game; treating the attempt as expendable would be a very bad course for the AI to take.
I'd like to see some measure of reliability, such as an average score, added to the game. Players would be free to ignore it if they wish, but I'd like to be able to push myself to be as reliable as possible, like the AI is being run through multiple simulations to evaluate its fitness.
Please add some manner of cumulative skill metric!
