>>> Prompt:
Update the map generation below to not only give me platforms, but add steep cliff
walls here and there, these walls should only be placed on top of platforms and should have
a bit of randomly generated jagged edges. The cliff walls should be blue (0000ff), for now.
The cliff walls can be up to 3 platforms high. The cliff wall can be at a steepness of between
70-110 degrees, but it must still be a little jagged (jaggedness should be configurable), so
you can use the number as an approximate to convey the idea. Both sides of the cliff should
go upwards toward a peak. Each cliff wall must be between 40 and 100 pixels wide.
Note that we still want to keep the existing rock and dirt platforms, just add the cliff walls on top of them.
Just give me the code, no need to explain anything, I just want to paste in the whole thing
with the cliff-wall solution in it. The cliffs must be separated by at least 100 pixels on the X axis.
