Hi! There are 4 places where a code can be found:
- The landline phone number
- Painting on the wall (not the picture frame)
- License plate number on the table
- 'honorable discharge' date, box in the kitchen
I'm so late to notice you've responded but thank you! I tried looking for guides everywhere because I couldn't remember where the last code was, and the only one I found just said "painting" and I didn't notice the other one! You're a real one for still replying to comments, both the story and animations are top quality so I'll be sure to check the rest of the game, thank you!
