NO JUMPING ALLOWED!
From the Super Mario Wiki
NO JUMPING ALLOWED! is the fifteenth course in the Story Mode of Super Mario Maker 2. It is set in the ghost house theme and in the New Super Mario Bros. U style. It is posted by The Gamemaster, and has a difficulty rating of 3/4 stars.
The level begins with a few Grinders and Stretches. After climbing a slope, Mario can head left, where he can try avoiding some Swinging Claws to reach a 10-Coin before entering a Warp Door. After passing some Fire Bars, Mario must head through a Warp Pipe, where he must then lure over a group of Boos so as to drop some Bill Blasters to ground level. Afterwards, a Monty Mole with a Cannon will appear, prompting Mario to get on and reach the next area, where he must stand on a platform above some Munchers to wait for a Big Winged Rocky Wrench to surface so that he can take another Warp Door. Mario must then cross a Big Boo followed by some Boo Buddies, followed by some alternating Burners. Mario can then have a Giant Bob-omb explode near a 30-Coin to collect it, then must enter another Warp Door. In the next room, Mario must throw a P Switch so that a Thwomp activates it, then cross some Bumpers to another Warp Pipe. Mario must then ride a Big Boo with a big Cannon to the Goal Pole.
"Here's a challenge: try to get through the whole level without jumping off the ground and landing! Any takers? Anyone? There's a prize for anyone who succeeds! Here's a hint—use to dash! Heh heh heh..."
