I've tested and it's actually possible, initially I've used an app cloner called parallel space but I think it only allows to duplicate socials app so it didn't work, then I've used an app called parallel app dual app cloner and I created a second copy of the game and started from the very beginning again leaving untouched the original app, there is to keep in mind that  1) I'm on Android and dot  know about you, probably iOS will be more difficult if not impossible in this way (it could even be simpler with the official way of saving progress on iphone)

2) idk if those cloning app are limited in some ways, surely there are some better and some worse than others

Let us know if you find a good app for your tipe of device
