they don't even need to touch the original background image.
they can add a semi-transparency layer (png image) above the background layer,something like
top layer ---------- <- cs weather effect
layer 005 --------- <- char
layer 004 --------- <- platforms
layer 003 --------- <- ufo
layer 002 -------- <- mount/building/background-near
layer 001 -------- <- sky
