Life Game
In my opinion life game isn't good but it's not bad either. The games and traps were kind of boring. In this genre smart concepts is the only way to make a successful story (e.g. Liar Game, Kaiji). In this, the characters were put in random life-threatening situations without any reason or explanation and there wasn't any kind of strategy that could save them. Their survival was based on pure luck. The only positive aspect of the story was the characters. I really liked the mc and his chemistry with the tall kind dude. Most of the characters were working together to survive and none of them died because of a stupid choise they made, which was pretty refreshing. Also the art was to my liking. Nothing extraordinary but decent nonetheless!
Jinrou Game - Beast Side
Waaaaay better than the first one. The main character's development was quite unexpected. In the first manga of the series she seemed to be kind of a weakling but in this one she turned into an antihero. Very interesting twist there!
Jinrou Game
It is your typical survival game manga. I've read lots of this genre so I wasn't really thrilled or anything but I kept reading. When I finished it though I really wanted to know the rest of the story. It is nothing special but all in all it is a good read.
