I like the game overall, but as has been mentioned before, sometimes with all the yellow pieces whirling around it gets difficult to see where you are exactly. Also, while i'm not sure how the program is meant to handle outside music, putting in my own MP3's didn't seem to work very well. A few cyan pieces came from the top, but most seemed to only come up about a centimeter from the bottom, making it rather un-fun. So overall, a 4/5
Good game, but the loop-the-loop has some major flaws once it gets over a certain size. I've had the last car detach and flip upside down in one spot on the straight away several times now, while the rest of the train continues moving fine.
