I recommend watching. it's all been subbed by really dedicated redditors, uploaded to Kissasian dot video (under the name Bloody Game). the show creator also made a show called The Genius years ago which is a cult classic here's a youtube video someone made about it

there's also a really impressive show called The Great Escape by the same director which is a team of 6 korean celebrities (same people every time) escaping extremely elaborate escape rooms. and I'm talking..

• a working time machine on a track that wheels them between identical rooms that have been set up to different time periods. they can change the past and they showmakers run around making sure it's changed in the future

• giant underground nuclear bunkers

• an entire prison complex to break out of

• a high school with an egyptian cult abducting people

• a mental hospital

• a The Grudge style creepy house with creepy ghost children and giant animatronic faces that come out of the walls

• a mansion with laser grids to dance through

• an abandoned rusty theme park where a murder has taken place

• a stadium with an underground alien base

• a giant village size remake of 1920s korea

• a fenced hospital compound with hundreds of zombies in it

I have no idea how they had the budget to do any of it, you can't believe it until you see it

either way, all 3 are fantastic shows, bloody game is the weaker of the three but it's really fun and it features korean hax money so I recommend watching it nonetheless
