Robo Rover is a free and fun game that requires very fast thinking.

You're controlling a probe roving the surface of Jupiter's moons. Your mission is to safely direct the probe to collect mineral samples for study. Problem is, that because of the distance to the probe you need to send your instructions to it as navigational transmissions.

There are many obstacles on the moon's surface. Some are simply barriers that will block the probe from continuing. Others are more dangerous and can result in your probe being fried or falling down a chasm. When that happens your probe will need to be replaced from the orbiting mission ship.

Not all obstacles are bad though; some are additional samples that award bonus scores. And as you progress you'll find more and newer obstacles on the moon's surface. Maybe even alien life!
