Thanks for the feedback! Honestly, a lot of these things should've been obvious when I was developing - tunnel vision, I suppose!
I totally agree on your last point - the player should've had more options for what to say to him instead of just starting off with something that incriminating, and it should've been clearer from the beginning that if you say you checked out the vault, you have to lie about who let you in.
Honestly, now that I think of it, the fact that I developed a method for spamming the movement keys so I could move faster during testing probably should've been a warning sign. Oh well.
Overall, thanks for playing the game and giving feedback!
