Kinda nice graphics, and that's all. Poor gameplay, bad interface (too many fading effects are TOO annoying), poor feedback, and VERY BORING flying sequences...
That background blur effect at the menu is pretty... but it is also VERY slow. It slows down the achievements menu too much, as well as the final score screen.
What makes this game so great? The stereotypical and funny characters? The fact it has good graphics, good music and good sounds? The good programming behind it, with no noticeable bugs? The careful programming+art when animating the cell membrane? Or because it is a FUN educational game? Well, I don't know, but I bet it's because of all of these!
