What I saw
This guide compares public written sources checked on 2026-10-28. No gameplay test was performed. Specific details supported by only one source are labeled below.
How the game is shaped
Most progression is exploration, conversation and item puzzles, with brief creature encounters and a shooting sequence. Follow the scene objective and room description when guide chapter numbering differs.
Early tasks include the cargo scanner and door, then the pre-crash birthday cake. Later obstacles include the loose sweetener packet, the blind-beast maze, the vent and graveyard encounters, and the FEAST valve scene. This hub is a puzzle index rather than a complete transcript of every chapter.
Where people get stuck
The cake and birthday mocktail use the kitchen dispenser. The later Swansea drink needs a loose packet under the bedding. For Cheater, enter cargo code 4517 before acquiring the scanner. The valve guide has one accessible written source and no independently verified rotation sequence.
The three chases are on their own page: do not sprint at the blind beast, keep moving in the vent, and listen in the graveyard.

Questions
Is there a Mouthwashing walkthrough?
Use the linked puzzle and encounter guides. Each names its direct sources; single-source steps and the valve guide’s limits are marked.
How many chapters are there?
Guides count through the low twenties, including odd “bizarro” chapters. The in-game select is the authority when a wiki skips numbers.
What is the cargo code?
4517, after you scan the door. Entering it early is the Cheater achievement.
What is the sweetener code?
2341 on the kitchen machine for the cake or birthday mocktail. The loose packet under the lounge bedding belongs to the later Swansea drink.
Do I need a video?
No video is required for the verified codes. The valve page describes only the monitor rule because a full rotation sequence has not been independently verified.
