Fun shmup! I liked that you don't move Up/Down with the d-pad like other space shooters, it makes the Y axis feel more deliberate in how you have to move. This has a lot of potential, especially with the creative sciencey premise. :)
My main critique is that the fire sound was very loud, it overshadows the music. And the music is really good, I love the echo-y melody on top of that crunchy bass and the drums.
