I played this all the time in school! It's pretty easy, but it seems a lot of people are having trouble. As a word of advice, remember that triangles are the most stable and structurally sound shape.
Not sure if my mouse is trashed from overuse or frustration, but I finally beat it. While the music was mostly enjoyable, it was a bit frustrating that near the end of 2-X and 3-X, the music completely drowned out the baseline of the more difficult portions, and had to do it based on visuals rather than sound.
