Nice, kept my attention enough to try it twice (~2:30 then ~1:30). Why do you make the user write their own time in order to save it? Is that some technical limitation or part of the game design for some reason? I always find these games to be neat when they show detailed stats of your performance, like a probability distribution of everyone's (best) scores and which percentile you fit in etc.
Would be neat if the goods were selectable with the keyboard.
