The only thing I smoke is mid.

That's a CS:GO joke for you.

With the Itch version, there are 10 codes in the game. Here are the clues to them—if you just want the codes themselves, they're not too hard to find.

1) Day 9, Paige/culprit talk.
2) Leet speak.
3) Day 13, Paige talk. Pre-laptop
4) There are 4 hidden numbers in the Escape Room, unrelated to the gate code
5) Bonus color puzzle after completing Escape Room
6) Pervert's Password - Mentioned by Paige on Day 15
7) Flashback on Day 15, Paige is weird
8) Group chat on Day 16 - Your Master
9) Completing all the Paige Puzzles and then getting the bonus scene and choosing a certain choice at the end
10) Day 17, Mess Hall. There is a 4 digit code on display throughout
