Use space bar to fly between the pipes! No cheating. These gifs can become playable games if you code the players and enemies yourself. You just need to change the costumes of the stage and the stage becomes playable like magic. This takes the complexity out of level design and allows more focus on game making.
Thanks to https://scratch.mit.edu/users/brickbattle/ https://scratch.mit.edu/users/gpett1000/ https://scratch.mit.edu/users/bplayer37/ and https://scratch.mit.edu/users/kirby115/ I created gifs by modifying their games to remove players and enemies and recording a controlled playthrough.
