This is basically just a race but on a much bigger scale. The screenshots below are just an example, you could do abolutely anything. Below in the screenie, I have wired the mode gates so that they open and close, then players must go through the teleport to the second room; try to get through the random banzai teles, over the hammocks, then back through the teleport, through the trees and pods. The first to sit on the yellow inflatable wins.
A varation of this could be Relay Races
where the players are in teams. The players will sit in a line with the person at the front going first. On go the first player will run to the tele and go through the maze in the next room. Whilst this is happening the other player(s) should move up and get ready to go for when their first player has sat on the inflatable. The first team with both players back wins. This could be on a 3 wins = prize system. If you like sticking to one room rather than using 2+, the players could race from one end of the room to the other with obstacles in their way. At the end of the room could be either a lert which the player has to set off before racing back, or a tele linking back to the start of the room.
