If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
You are Tor, a large, gentle natured Martian living in space and solitude in the Martian wilderness. Unfortunately, video games don't often go on like that for long. Earthlings have finally visited your planet and are bringing with them their litter, rap rock, religions and fast food restaurant franchises. You grab your state of the art SmashMaster 4000 and set out to shut down their invasion at the source.
