Just finished squid game,

As The God's Will, a Japanese film. It's funny but gory as hell. Check it out.

I wasnt expected a korean film would be like that but i watched it before movie become famous. Highly recomended!

Theres a lot of ?death game type shows/movies especially in Asian cinema. Definitely check out Alice in Borderland and Battle Royale as others have suggested (the Battle Royale book is much better if youre into reading though). If you look up ?death game shows and movies there are a lot of great suggestions
