Absolutely, we know rollback is crucial for a dialogue-heavy games like ours.
Right now the rollback function only works on PC with a mouse wheel and we intend to add it as a button to the new textbox, so mobile players would get the same level of comfort.
We plan to add Rollback, Skip, Hide UI, Quick Save/Load functions to textbox. You will also be able to hide them in the settings, if you want to use Key Shortcuts instead.
