You've been summoned to extract rare minerals from asteroids. You have traveled to a legendary valley, in which asteroids fall every 10 seconds. You have to use your trusty rifle to move the falling asteroids into the mineral extractor. But beware, a rivaling company has sent killer robots to sabotage your work. How many asteroids are you able to process?

UPDATE I added a HTML5 version of the game. The shader compilation makes the game stutter a bit when the shaders are loaded for the first time, but after that the game should run smoothly. I also enabled asynchronous shader loading, to combat the jittering issues.
