i would say chest refilling but to prevent camping i would like that it stopped at a certain moment
Glowing would be coolI think it's good to have time like Hypixel. Like 20 mins for the game and if there is no winner there can be mobs or the blocks can disappear and more. It's annoying for someone to try to find the last player who is camping or maybe when there are 3 or 2 players left the time will go automatically to 5 mins ( if the map is bigger the time can be more ) or maybe when the time is out every player can get compass and every player will start glowing
( Glowing like when someone got the flag in CTF or when someone gets shot with glowing arrow )
