Here's a few ideas to make it more accurate
Lobby(ingame):
-The entrance to the games should be in the left door like in the show
-The middle one for the guards
-Each player died = A bed disappears
-The drawings in wall should be hidden behind the beds or idk
-X and O lines (only decoration)
RLGL:
-Larger map (this suggestion sucks but in a pro server would be cool)
-Roof that closes if the game ends
-Start and finish lines instead of a invisible wall
Penthatlon:
-Bigger circles (the map should be larger to do this)
-Jegi gameplay should change (its very confusing for new players and they always make my team die)
-Harder ddakji
Mingle:
-Lights off when the platform starts spinning and another lights but only in platform
Msrbles:
-More game modes
-Larger map
-Accurate map (in the show there's more than just walls) in the show there's buildings cuz the map its a suburban city
Tug of war:
- There should be 4 teams so only 2 teams remain alive and there's 2 rounds
RPS-1:
-cool music
-more tense ambience
Glass bridge:
-Change the pipes color to reddish pink like in the show
-More time
Squid game:
-In a pro server changing the gameplay to the original squid game gameplay would be cool
