Dust

Dust is awesome. There are lots of things you can do on it. My favorite thing to do is the battle of the elements. You put clone on both sides. You put magma on one and water on the other. Then, you make a water player and you shoot water onto the magma. You try to get rid of the magma. If you get rid of the magma by water, you win! But if the magma evaporates the water, you lose. Warning: magma gets rid of water faster than water gets rid of magma. Just look up dust on google and select the one on notdoppler. Have fun!
