I’ve read this already too but thank you so much!!
'Alice in borderland'-- amazing death game manga, you'll love this
'Money game'-- artsyle might be a bit simple but it's a good death game of sorts
'Judge/doubt'-- they're two different mangas but are related i believe. They're alright.

^ werewolf game but with an extremely gorey twist & its actually pretty good
Death games or Survival games please I don’t care if it has romance or not. I’ve read Tomodachi game, Real Account, Kamisama no Iutoori II, and Battle in 5 seconds.
