Purchased the android version and can't save so I can't make any real progress (If there is any). If the save hasn't been implemented this seems like a waste of a tenner right now.

Save has not been implemented. At least not in the versions they provide to us here on Itch.

but we need it

Kinda regret actually paying for this game atm. Hoping it gets an update soon because it's made well, it's just pretty vanilla right now.
