The Universe and Randy

A game made in 72 hours for the GameMaker Communiuty Game Jam #16.You play as Randy, a clumsy space traveler in search for Crystals. To get crystals you need to land on planets and harvest them. But flying around uses fuel. You can harvest fuel from other planets but they also contain sand that ruins the ships instruments. As time goes on it gets harder and harder with more instruments breaking and fuel running out. How many crystals can you collect?
