Simple Things Can Be Mindblowing
Such as the realization that the little colored arcs weren't background decoration, but giving you a heads up on the path enemy ships will be taking. Very nice.
Of course, one nitpicky problem is that there is no back button if you click the wrong level like some kind of moron... Such as me... God I'm so ashamed (fortunately, pod spiral shots worked out just fine).
I owe those side pods blocking shots my multiple lives. My only game over was because I got greedy trying to get scratches from huge clusters that could blast away all my shields at once... And I kept doing it.
As for all the people talking about 'open up the screen', I've never played any of the "Real" bullet hells so maybe it's more important in those? Screen size was fine to me, but then I'm way to paranoid about where ships normally come from in shooters to ever go to the TOP of the screen. Though, there were a few times I wished my RedRum and Shield bars were not blocking my view when hanging out at the bottom of the screen.
Of course, the fact I don't play any of those "Real" Bullet hells are probably why I felt the difficulty was just right. Enough to make me pay attention and hold a healthy respect for the bullets I'm trying to mooch extra lives off of, but not enough to make me want to stop playing after a 10 minute long seizure inducing bossfight.
