Huh--when does the "solve case" button come up? I've just ended the day a bunch of times and I didn't see it.
I haven't been able to open the safe, and none of the clues I have will open it--don't I need to do that first?
Yes, unlocking the safe is triggering this button. You need a code for doing so. You can find it in the security camera photo. Wish I would have had more time to "envelop" all this with more logic and deduction. Was watching you playing these games yesterday, and constantly thought: "woa... these games are miles ahead of ours in terms of coherence and proper conclusions".
