Honestly, when you get sent an app to test that is about transforming yourself or others, you should be extra responsible when playing with it. Yes, sure it must be a joke, it's not real, that's not real things, but.... still, even if you doubt it, why press your luck with jokey inputs. I mean, it also doesn't HELP when it glitches out and changes some of your settings, or changes your intended changes into something else, but... just... be cautious!
But yeah, wanted to take a stab at a plush tf again, and had some old resources/refs that I could use as a base, so went with it and tried to improve from the last. And I remember some CYOC adventure stories... Chronivac or something, and thought I would do something inspired by the idea of a machine/app to change yourself. It was fun to play with the idea.
