Smash Crash Teroids

In Smash Crash Teroids, you are the pilot of a 'space sweeper' ship. You have just received an assignment which will take a very long time; you are to clear up an entire asteroid ring in a nearby star system! Asteroids don't shoot back, of course; but this does not mean that they are not dangerous, and that is why your ship is equipped with a very strong shield that is capable of protecting it from an impact with even the largest asteroid. However, shield do require charging and each impact will drain some of the charge, which takes time to replenish. Take care not to allow all the charge to be drained because at the time your ship will become vulnerable and any impact will destroy it. To move your ship, press the left arrow key to turn left, right arrow key to turn right and up arrow key to fire forward thrusters. There is no stop key and the only way to stop is to set your ship facing the opposite direction and fire the forward thrusters again until your ship stop moving. To fire your ship weapons, press space bar. From time to time, a special power pod of green color will be sent over to help you with your work; when you see one, move your ship to fetch it and your weapon will be upgraded.There are various kinds of upgrade but they all last only temporarily, from just a single shot to several seconds. There are also alien probes that must be shot along with the asteroids. You have a total of 3 lives and if you lose them all, the game is over
