Is there a way to restart day selector and such? Even though I just downloaded the game, everything is open and I prefer to proceed on my own. Like unlocking things and scenes.
Day selector (and scene selector (and do over, to some extent)) are meant as play assist tool, not unlockable rewards or progress trackers. They also have no game impact, and are not required to complete or play the game, you can start a new game and just never open/use them. Same is true with mind blowers, it's there for player convenience, not as an unlockable reward/task.
Personally, I very much dislike locked systems in games, and most players tend to download a patch, or get a "full save", to access everything. I decided to just have it open from the start (for a number of reasons). But again, you don't have to use any system (outside of clicking to the next dialogue) to play the game.
