That was really hard, I like it! Very memory intensive, I managed to get 2530! My only issue with the game was waiting at the end to see the score. It goes up about 500 / second, which meant waiting a few seconds for the points indicator to update and then again for the highscore to change. These indicators should instead work so that they do, say 100% / second, so that each score, regardless of size will take 1 second, and smaller scores travel slower than big scores. This is very minor though, so good frickin job!
