The aim is to not die (wow..) and to gain points To start, press the 'start' button (how poetic) or press 'a' (you might want to wait for the rocks to pass first, then press start). To shoot, press the 'space' key. To move, use the 'up' and 'down' keys. The crystal only appears once a game and is worth 200 points; you can hit it with the bullets or just bump into it. If you hit the rocks, you get 100 points. If you get hit by the rocks, you die; press the green flag to continue playing......that's about it.
