Out of all the flash based mouse controlled games, this may be the smoothest. However, I am getting stuck in endless mode. I don't know if it is just me, but I get exit out of Endless mode. The menu buttons in the top left gray out during game play, and when I die, even though they come back, I can't click on them. And the only thing I am able to do is "Click to try Again." If there is something I need to do, it should probably say so.
