Fun game so far, haven't got very far though but that is because I'm stubborn to put it on an easier difficulty.
My only complaint is that his giant ball of death is incredibly fast for how big it is. It's easier after the first time you see it but the first time it's insta kill imo.
Maybe when he switches to the phase, before firing the first one he does a slightly longer charge animation.
The rest of the stage is fine, I do think power ups are too sparse.
Before the second(?) midboss there is a laser grid section where you gotta wait for the lightning to go away. The last grid is really unfair, the 3 times I've reached it I got hit by it. I also don't think their bullets should go through walls, that is unfair.
Mid Boss 2(?) - The eye fucker
This guy is the reason I took a break for now. He is just brutal.
The only real attack I have a huge issue is when he throws the giant lightning rods at you, Most of them are practically impossible or sometimes literally impossible to dodge.
Even when there a tiny gap if you're really good and can squeeze under. You cannot do that AND dodge him striking lightning at you.
Also not really unfair but I do wish the lightning strike hit the wall.
BUG: If you beat the eye boss and die at the same time. The music after the boss will overlap with the main menu music.
I also think the homing attack is criminally weak. It is really bad at tracking enemies and will follow a single enemy even if they go behind you. If the enemy is remotely fast, you will never kill it. Which is terrible since 95% of enemies are remotely fast. I will kill like 3 enemies per screen.
