One small issue
The game is as perfect as it can get; however, the comparative scores with the best of other users is unrealistic. Often it shows that a game can be done in 25 seconds. The average person takes 2.5 minutes or more usually struggling to stay under 4.0 minutes.
I would like the comparatives be meaningful and thus, worthwhile.
