2 things just came 2 my mind:
1st: If there was a preferred seating option, I would have less misclicks and less eye cancer
2nd: It does not distinguish between marginally bad and horribly bad decisions. I would like to get the feedback "good decision", "bad decision", "okay-ish decision". I know it can be compared to the correct answer, but a simple red "wrong" vs yellow "wrong" would help there:-)
Ideally the results in the end can be written as "loss vs perfect player"
