Shogun: Bullet Hell Shooter

So I'm apparently ranked no 1 in Canada and no 5 in the world on level 2... for not clearing it. What species is this game made for? It makes Cave games seem simple. The demo makes it seem possible, but on buying it I found most of the game is just inaccessible. I bet it's as well crafted and polished as the first level, but I'd need like 20 years of hard training to check. Also, putting shot change and bomb options in a popup menu that doesn't pause the game is absolutely infeasible in a game like this. I thought I'd just get used to it or the game would be paced to compliment it, but no - It's like driving a car that's controlled from a command prompt.
