You know , this game would be a bit better if you could have the ability to press a button to back up and undo a mistake you made like other games here on the platform
That's completely irrational it says it's android compatible if you can undo choose on PC it should work on android otherwise say it's not compatible it's all or nothing
I'm way late to this but, for all ren'py games that allow rollback if you go to the options there is a setting called rollback and it says left or right. pick one then it should rollback when you tap the side you picked.
