It's very pretty, all the light and particle effects are really nice (even tho it can be difficult to distinguish what can hit you and what cannot). The sound is really harsh tho, the firing sound tends to click several time at the end, so when played a lot of time it's very annoying, also you have some sounds that clips, so it hurts the ears. Finally, no music un unfortunate. So yeah, you should work on the sound, and the clarity of the visual and it would be perfect!
