Ashion IX is impossible (trotrods)

[fweezel]

I finally beat Sulphagne after getting killed over and over and over, and make it to Ashion IX where I have to fight stupid things that shoot you every time you attack them. Fine, I just won't attack them OH WAIT THEY SHOOT AT YOU ANYWAY WITH ATTACKS THAT FILL THE SCREEN!

How am I supposed to beat this stupid level?
