I like the idea of the weapons being out of control. I think you should have focused on that for the theme, as opposed to the story of the player's ally's being out of control.
But the weapons in this game always feel in my control. Once I memorized the colors, I always picked up the upgrades I wanted and left alone the bombs i didnt like. Since even the base shot is a 1 hit kill, I found it was better than the slow moving bombs.
Also I never found a use for the dash. The player is already fast and responsive. I could dodge the enemy fire as long as i saw it coming (which is a bit hard since my lasers and theirs are the same color.) The dash just made me go out of control.
