It aint easy being green... or so said a wise frog once, oh so long ago, in a galaxy far far away, yadda yadda yadda. Basically, in this game you're a green thinga-me-bob-disc-orb-whatevah. It is your solemn duty as a member of the green race to pick up the yellow thingies as quickly and efficiently as possible. Of course, as one might expect, you have to avoid the red ones like the plague. Think of them as ebola in game form. You do not want to go near the reds, you do not want to touch the reds, you do not want the reds to touch you. Run like the wind if a red thingie comes your way.
This is a very fast paced game with various challenges, 30 in fact, not to mention a bunch of medals. They call the game green-it... but really, you're actually yellowing yourself instead. Maybe it should be called 'yellow the green thingie' it instead. But that is a matter for another time, another place, another dimension.
Use the force and capture all the darstadly yellows and any other color, other than red. Happy gaming!
