I have recently made a roller coaster at my island and I think you guys should check it out. Just go to /warp L7G and follow the path to the track. Press the button next to the dispenser to spawn in a Minecart then once you are in the Minecart move forward (with W of course) and enjoy the ride. PLEASE do not spam the minecarts and push them on the track when they are empty as it can affect the ride for other people. If you do try it out then please let me know your opinions on it. Thanks!
