The depth of the walkthrough was muuuuch more than I was expecting and now I feel a little bad for comparing it to another game I played with one.
I can't imagine how much time it took. I think the biggest and best example is that first punishment with Hikari. There's so much more to it than I was expecting there to be, it wasn't as simple as a "Did you spank her? Yes/no. If yes you didn't take it easy like you promised" sorta scenario like I thought it was before seeing what was said in the walkthrough.
Couple typos I noticed:
When the Director is no longer in the call with their superior/sponsor he notes how his computer was turned "of" and not "off"
With the Walkthrough when it comes to entering a relationship with Riley in the Reject hint/description it says "Closes submission route open"
