just to let people know,
you can totally fuck with the values and flags for galomax, goo biomass, and goo qualities of body parts to give yourself the ability to freely modify measurements in-game without actually being goo.
the only thing you have to look out for is maybe your hair or some other bodypart "re-gooifying" probably due to ticking the flags. but, simply pop the save back in and fix that and it doesnt happen again (as far as ive seen)
this coupled with the undo feature means you can walk into a scene, the "girl" looks disappointed that you're to big/small, ya rewind time and double or halve your package and walk back in. i cant imagine what horseshit you'd have to do to make this happen legit if at all possible
