Hi, I would like to purchase this game, id like to buy the itch io version because it has android version of the game while steam isnt. My biggest worry is that when I complete it on android, could I backup the saves on to a file and send it to my PC for storage? Or are there cloud saving system?

Hello, technically it should be possible though I've never tried. The save files for PC can be found in the Registry Editor ; User/Appdata/LocalLow/Pinktea/Realms Of Bondage
Android save files maybe somewhere like: Internal storage/Android/data/
