also i suggest adding maybe a ultimate move set based on your color or just a abilty by charging it up by killing other in a three round game play like
red: super ground pound
orange: edge (will teleport the opponent to the top of the map and do some damage)
yellow: yeet (yeet the player)
green: laser (aim at the player and kill them
blue: freeze (the opponent cant move)
purple: do damage to them over time
white: assend abilty one shotting them
black: super speed punch
grey: one shot punch
