> maybe with some tweaking the idea of the player entering pure surviving mode isn't bad for a bullet game.
Yeah, I mean like I said it's not like it's "impossible" to make it happen, but you gotta remember that dodging and shooting is something that the player is already doing at once all the time in a bullet hell. You just take away one of those things... and the player is just left doing what they were already doing, just with even less to think about at once. So you gotta give them something in return. The idea I randomly threw out there of "grazing to rebuild your Aura" gives the player agency, since now they're not just waiting but actively thinking about HOW they dodge and have a decision of risking getting closer to bullets to get back into the action; that's just an example.
Also nah the angel being a demon/demon looking like an angel vice versa isn't a huge deal, that's a pretty classical cliche in demon stories (like devil may cry or devilman lol). I do like the whole demon and cult aesthetic, but I didn't see the "unstable" part in it all; maybe if it was more "intense" with more monstrous designs it could've fit a bit more.
