Much better than the prequel and (obviously) provides for a very enjoyable experience.
The new features are great, especially the way to play (moving around instead of closing eyes). It also punishes the lazy, "turtly" ones and favors agressive play, since being small is the only way to dodge lightrays later on - thus forcing the player to constant move around and graze the lights, risking a game over, in order to mantain smaller size to avoid a 100% chance of a game over later on.
Definitely a good time waster, could use a highscore table too.
