NO SPOILERS IN THIS REVIEW :)
Personally, I found this a really amazing anime and recommend it completely. If you enjoy dark, psychological anime with a drop of romance or ship couples easily; this is definitely one for you!
DISLIKES: The start was very slow. I watched it all in about 2 days, but I found it took me quite a while to get really into it; about a good 6 episodes. This is the ONLY reason i can't give it a 10 overall. However, when i got into it, I REALLY GOT INTO IT!!
LOVED: I loved all the themes it included, especially the survival game aspect and the fact it's filled with very unexpected twists which are extremely intelligent. The characters (especially YUNO) blew me away with their likability and their uniqueness. The art is beautiful as well; if anything the best I've seen in a anime.
OVERALL: This anime is a MUST WATCH! My advice is that you make a pizza to entertain you through the first few episodes, but after that you'll get so into you will most likely throw the pizza out the window. This 100% is my favourite anime to date!
