MINI SPOILERS AHEAD | NOTHING GAME REVEALING OR ANY PUZZLE SOLVING SOLUTIONS BUT JUST IN CASE, DON'T READ IF YOU'RE PLANNING TO PLAY THE GAME AND AREN'T HAVING ISSUES WITH MOTHER'S COMBINATION CODE!!!
I know, it stumped me at first really well. I thought I had to search around for a number, but they never give you a "number." I know a bit of a hint, but I don't want you walking around looking for a number that doesn't exist! There are clues, hints, but there isn't anything solid like most games where they give you the number on a found slip of paper or a character tells you it. The answer is there, but you need to think! That's one thing I loved about this game! It had me thinking the whole time in a subtle way that felt like a realistic mystery.
I recorded my game play of this game, and I'll upload it when I'm done editing it (my audio was an hour long, mostly because bugs had me exiting and restarting the game). This game is pretty good! I loved it. When you figure it out, you'll see what I mean!
