Completely Ridiculous.
Welp, Casual mode might as well be called 'kill yourself now mode." it was so hard in fact that I didn't even bother attempting the actual hard mode. It could be a fun game, but since 90% of the time the screen is completely covered in enemy missiles, explosions, and so much other shit that your left not even able to comprehend what's happening. You spend so much time with your eyes locked on your character attempting to dodge every little blip on the screen that you can't even tell if you're actually hitting anything. I made it all the way to the 2nd stage of second boss, only to realize that there is absolutely no way to hit it with the yellow weapon because it homes in and tries to hit down all the missiles, but since there's roughly 90 missiles on the screen at any given time it's impossible. Sooooo... I'm stuck... until another weapon shows up -- and even if it does there's no telling that I'll be able to reach it without being completely demolished.
The weapons are terrible. While they are all useful in certain situations they quickly become useless. The starting fire weapon is useless since the silver one does the same thing only better. Yellow was the only effective weapon in some situations and than in others is became completely useless. Blue was only good for its fully charged beam, I wanted to use it to sweep the whole screen, but since you're not invulnerable while firing you'll end up dead if you try. Silver was the only competent weapon,
