mandelbrot parkor sounds like a good idea actually, you can have it generate a fractal, then have people get from the bottom to the top or somewhere else
while reading this I just thought of an idea on how to make it randomly generate the settings of a fractal, so there could be like random seed parkour, and the less amount of blocks you edit, the better your score is or something.
Some are just the 2d version spinning, burning ship looks that way but isn't, tricorn can be made one cross section mandelbrot if you conj() only one axis.
