Select from 4 different difficulty parameters to have the game change from stupidly easy to impossibly hard. As the difficulty increases, so does your score multiplier! Touch the objects that match the description at the start of the game. Don't touch incorrect objects or your score will drop. If you fail to grab an object that matches the description, you lose. Also check out the asteroid dodging mini game Collision Course.
