You gave us a setting. Is it a Planet vs Planet fight? Is it Colonize the planets? Or by world do you mean plane? Like different dimensions?
Tell us whether it is Free For All, Teams, Co-op
If it is planets, maybe a gravity system which slows you down/speeds you up
idk if ur gonna use this but you could have like a area with some text below
for example
one way out
have some plants and maybe a item spawner with a zapper (ofc use walls so u can’t get in)
then have the text say the game name
then have a button to teleport you there.
I just realized, If i have the setting at cooperative, I won’t be able to do the team games, and I think there is a way to do 2 things at once with the button, right @RektRainbow? I am going to use that if this works! I could have a team switcher and a teleporter
