I think that for treasure wars it would be interesting to disable certain items
ex: doing a sumo, turning off swords and snowballs
you should also be able to toggle/adjust more things
ex:
-cps cap
-damage amount
-mayfly
-forced treasure
-treasure size
-spawnkits
-amount of vertical/horizontal knockback
-hitbox size
-potion effects, like an effect that can be amplified that is permanently on
-items from other games? (knockback nemo, seeker smasher 3000, Regular Boom box)
-replaced block (this is probably dumb and hard to do, but the idea is a specific block, if placed, turns into any specified block ex: jump bridging on ice, concrete becomes lava lol) to specify, you could search for that block using the search bar like you did with costumes
you should also be able to do more things related to managing them:
-people in parties should just be warped like regular games
- they should auto close after about 45 minutes so there is more space
also whoever did “close” and “close but yellow” you are a legend lmao
