I know, let's make a bullet hell game where your hitbox takes up half the screen! And just because that doesn't suck enough, let's drop instadeath bombs that cover the WHOLE screen!
How did the turn-based tag get voted down? That's what this is, even in variation- one of those lousy, turn-based games where the characters just stand in one place and you click buttons to do your 'attacks'. So it's got a fancy name now, 'arena combat'? All the same to me - pure suckage.
