Nucleus

Nucleus takes quite a bit of hand-mouse coordination. What starts out as a simple concept at first is in later levels taken to its most challenging extremes. Kind of like a combination of jump rope and Duck Hunt, if the rope were electrons and the ducks were their positive and negative charges. Or maybe it's more akin to passing the baton in track and field, but more complicated than just running in cirlces. We lack words to describe the utter simplicity of this bemusing and challenging diversion. If the Duck Hunt analogy held up, the rope (spun Double Dutch in later levels) would be turned by the rascally dog. Fortunately the analogy fails flatly, so the dog will neither giggle nor bark at you when you mess up.
