Answer 1

The biggest problem was that I couldn't really see.  I had liked what I thought would be the any% path, until I realized the real any% path was just to use dustkid or dustworth and go directly up.

Answer 2

If you want you can add me on steam and have me test maps for you, I like the route but it is difficult to see.

I just went through it a bit and this is what I came up with:
dustforce://installPlay/3484/Cave-system

It's a good idea for your first few maps to mess around with the editor a lot so that you can get a feel for it.

Answer 3

Answer 4
