How to Cheat in v3.0 (ONLY for old fans) (Patreon)

ONLY for those who've finished the game a couple times before, and they just want to go back to see some new stuff. Otherwise, it will definitely ruin the game experience for you. Make sure you are playing v3.0. The cheat room is at top right of the underground sewers. There is a gate and a passcode panel. Enter 2002.
