Story - The story in this one is pretty well done in the fact that they show all the characters and how each character has their own window into the future. I feel like they distributed the story well and it was what i expected to watch. There aren't that many BIG plot holes in this one as in the beginning i was confused as how there were 3 bodies in yuno's house, but then they explained how and why that was.
Art - The art style here is alright. It's very dark and gloomy for most of the anime. It was different than your traditional "Big eyes, small nose" type anime, but i still enjoyed the scenery.
Sound - Sound design and the OST here are pretty damn memorable, i love the first theme song and i feel like i could rewatch the anime just for it. The diary sounds when the future changes is also very memorable. I love how they also use different sounds for different diaries when the future changes.
Character - Starting with yuno, she was, for the most part very unpredictable, you didn't know if she was the bad guy or the good guy for MOST of the anime. Where as you had Yuki, who is more scared of his own girlfriend than a death game he's in. But i do understand why he is so scared, as his life is almost always on the line in this show. The other characters are memorable for the most part, i really like Murmur's character as you think she's just Duas' servant, but find out later that she is the founder of the game.
Enjoyment - The overall enjoyment is great. Not much else to say here for the most part.
Overall - This anime is one that a lot of people don't know about. And if they do they sit on the hate side or the great side of the fence. For me i loved this anime and i recommend you watch it yourself. It can be Cliche in some parts, but overall it's unpredictable.
