Simple I see cute anime girl, I like. She is petty, has sass I like. The idea is pretty funny, you basically have to MLG, 360 No Scope bosses into oblivion and the overall seriousness of the game vs the silliness of the game is a nice combo. Overall it plays a little slow in terms that I think it could speed up, though that would conflict a little bit with our ability to aim. But I think it could turn out to be a better game with some tweaks. (We like bullet hells in this household.) I did enjoy it, and I look forward to what you make in the future!
The visuals do remind me of Arknights which I am also a sucker for.
