Here is my entry! Arrow keys to move, space to remove shadows (are there shadows in space?). W and S to change size. Information (please read): Named after one of Saturn's moons, because that's what I thought the spikes reminded me of (without the centre bit). The shadow effect give depth so it looks like you shoot under the ring like it's meant to, but there is no shooting yet. It has 2 (local) variables, is that ok? The ship is hard to destroy although it is difficult to aim due to the rotating.
Entry for Leafino's spaceship competition. Not very good at vector, but gave it my best shot. 6/7/14 - Changed to have one sprite rather than 3 and size that you can change.
