Round II: Invitational 2019
From the Super Mario Wiki
Round II: Invitational 2019 is an official course in Course World in Super Mario Maker 2. It is a "standard" level published by NintendoUS, being the second level played during the preliminary round of the 2019 Nintendo World Championships. It is set in the ghost house theme and in the Super Mario World style, and can also only be played in co-op.
The level begins with a split path, where the players must hit ON/OFF Switches in synchronization to enter a Warp Door at the end. In the next room, one player must throw the other into a Swinging Claw to reach a P Switch above. After activating the P Switch and jumping across some Note Blocks, the players must use ON/OFF Switches to proceed. The lower player must then use another P Switch to allow the upper player to proceed, then throw a POW Block at a Rotating Block to reveal a Trampoline that the upper player can use to reach a high ledge. After the upper player hits on ON/OFF Switch twice, the lower player must pass another POW Block to the upper player to release a Beanstalk from a ? Block and thus enter another Warp Door. The players must then make synchronized jumping and hitting of ON/OFF Switches to avoid falling and enter a Warp Pipe, where they must subsequently make use of a self-triggering ON/OFF Switch to ride a Lava Lift to another Warp Pipe. Afterwards, one player must pick up the other and jump to throw the carried player to the Giant Gate.
