Like the jump game too would recommend turning pvp using snowballs though (i.e. 16 when you "revive".start) since killing is quite pointless in the game and snowballs are easier to use the limited amount means you can't just infinitely keep throwing them either ^^. having teams would be harder since you would need to determine some things first 1. when does a team win? 1 player finishes the course or all of them? how do you prevent players from sabotaging their team on purpose/ by accident? the difference between team could be simply done with colored leather armor or chain/gold armor like the currnt pvp games.
to close off how do you determine the winner/ prevent doubt about who finished first?
