Solo Bullet

So the idea is fine ,but but a bullet hell has slower, smaller and lots more bullets. This is like if you are trying to dodge one bullet you need to be careful and in your game is "have half a second to react and 5 seconds of break". U know what i mean.( An idea i just came up with: evry stage is a boss and u need to kill all for ex.: The first two dudes will shoot and move to a diffrend position and repeat. U will have to shoot both of them to go to the triangles). For the visuals u can make an update OR make the back round black and everything else the same color. And for last can u PLEASE add "exit to menu" and "exit to windows/linux" buttons?
