Story- Trapped in a world where death in a video game is real. MC is op and doesn't show his true powers and meets Asuna (Marry Sue) that is also op. They come to like each other throughout the series. Btw MC is op.
Art-Nice colors and good amount of frames to compliment.
Sound- Nice music to compliment the important scenes like when they're fighting
Character- MC is op. He is op for no reason. He way to powerful when you compare that hes only a kid and yet people who are older than him are far weaker and scrawny. Asuna is a marry sue. Every action she takes is unquestion and she is almost perfect in every way. There is no "character progression" because there is none to progress since they're like max level already >_>. Every other character is non existence because no one cares about that.
