Full disclosure: I suck at bullet hells. I know Dogtopius knows that, but other folks flipping through the comments might not.
I love the concept here, but I found the difficulty insane; I couldn't even get past the first level. Even the first boss is similar in difficulty to the later bosses of previous games in terms of what it's throwing at you, and on top of that I'm trying to juggle the camera charging and get in for a photo before I get annihilated. It seems to be less forgiving than previous games as well, with no lives system and the camera not quite a substitute for bombs.
I'm not convinced that there's really enough room for the camera mechanic, but in addition to sucking at bullet hells I also suck at multitasking.
I gave up pretty quickly, and it's kinda too bad, because the screenshots of the Ren'ai part of the game look really good and I would have liked to have seen that.
