Just played through the game once and quite enjoyed it, thanks to the devs and everybody who worked on it! :D

Most VNs let you go back in the dialogue and choices by scrolling, making it easier to explore different dialogue options than constantly saving and reloading. When using the mouse wheel in RE:H the menu opens. (Very occasionally one line of dialogue scrolls back before that.) Seeing saveslots are a thing I'm assuming this isn't an intentional design choice to make "your choices matter!". 

Are there different controls for rollback, or is it simply not available? 

Would love to replay the game and explore other paths, but I'm also notorious for accidentally misclicking, or just curious what characters say to a certain choice without actually wanting to go down that route, so I'd greatly appreciate that convenience :)
