Lol, that's embarrassing! Seem to have lost myself in the many tabs... xD I'm making an attempt to comment on your game this time! :D
I got 400 high-score, will make an attempt for a better one later! I liked this! At first I thought, "well, this isn't even possible, is it?" but I don't know if it was designed that way or a lucky coincidence that the game was kind on what counted as a hit. The speed variations and increasing difficulty felt just right and made you keep planning and reacting fast.
A superb high-score game, well done! :D
