The second season surprised me beyond my expectations. It had many things which I found missing in the first one. The games were now much more interesting and entertaining to watch. The character development was on point. Even the backstories of many side characters were shared, which added a sense of understanding and attachment to their characters. The "Queen of Hearts" level was my favourite as it was very convincing and even made me wonder what is reality and what isn't. I was very impressed by how brilliantly all these game levels were made and how much thought was put into making them. Some of the dialogues and scenes were really thought-provoking and excellently constructed. 
The only two letdowns for me were the unnecessary elimination of characters and the epilogue, as I really believe that the characters should have at least remembered each other. Because they were literally willing to risk their lives for their companions. I tried to understand it from their point of view and put myself in their shoes. I realized that I would have felt really lonely if I had known that I was the only one who survived. Furthermore, it made them forget about characters like Kyuma, who believe it or not,by accepting their fate, it actually helped Arisu and the others to survive. The same goes for Tatta. I believe it was unfair to their memory for Arisu and the rest not to remember them.
