The biggest issue for me is that the main cast effortlessly wins fights, there's simply zero tension when the heroes fight because it's clear that no one is actually in danger - and even if they were it doesn't actually matter that much.
The attacks are just flashing lights, no matter what is actually happening. One tanky dude screams "Anchor Howl" and it's just a flash of a green light that is supposed to draw the enemies towards him. I know it's supposed to be like in a video game but that doesn't really translate well to animation.
The general premise is kind of dumb. Due to how the world works everything the heroes do seems kind of pointless. There's no end goal nor any danger, it's literally "lol we're in a video game now". Hell, the main hero even says "there's no point in doing anything" in the very first episode. If there's no point - why keep on watching?
