These are crudely made warps.
Please place them in the "SecretFlasherManaka v1.1.3\CustomMissions" folder.
I've included images of warps that are likely to be difficult to find.
The two in front of the store lattice and the garden entrance and exit may be difficult to find.
I think you'll be able to spot the others.
Downtown 22 (3 inside the station)
Park 8
Apartment 4
Mall 1
Residence 1
The Y axis is height, so you can climb structures by simply adding 4, 8, or 10 to this.
I'm sure many people have already made these (especially inside stations).
PS:Warp area on the 10th floor of the apartment building. It's difficult to return from the rooftop. (It's possible if you overlap with the elevator.)
Equip your coat and then warp and fast travel.
Or make an emergency escape. (RP will be lost.)
These are the people who founded and developed the original warp area.
They're all amazing.
