Idk if the different maps will even be very different but my idea would be
"Reach all four areas/biomes (whatever you call them)"
Only would work for ILs if the maps actually play a factor in the speed

Good Idea, but when does it count as being in a map area? How do you figure out when to end the timer?

Only thing I could think of working for counting being in the areas is having to stand on a specific kind of block. Example : to be counted for being in the beach/desert area (in some maps) you need to stand on a sand block
but even then you would have to specify even further because there could be sand in another area...

Ending timer for this example would also be when you land on the final block in the final area.

You can't really retime standing on a block since you pick a video frame where the run ends.

Yeah im not sure then. I'll think on it and get back to you.

If anyone else ideas write them in this thread tho
