Speaking of which, I tried some of these maps out! (8000x8000 pixels, 522 path size)
Let me know, what you think
EDIT1: I just noticed, when I'm generating a Big RR map (8000x8000, Water, No Top Soil, Start Top Left) i takes about 3-6 seconds, right? But when I'm saving a map, it freezes for about 10 seconds, then I get the map exported. Weird right?
Also, a suggestion, make Start at Top Right, Bottom Left and Bottom Right choices for Rope Race.
