Overview

MOUSE is a Roblox horror game by Myriagone set aboard the S.S. Willie, a steamboat that vanished in 1928. You row out to the ship with your crew and try to escape before the Mouse catches you. This guide covers how to survive your first run, what changes in harder modes, and how to earn all four badges.

Hardcore mode — what changes

Table

In short Hardcore stacks four penalties at once, making it the hardest badge to earn.

Hardcore mode runs by a completely different set of rules from a normal escape. All four changes apply simultaneously, so there is no easing in.

Lives	one only, so a single failure means starting over
Hiding	not available, removing a key defensive option
Flashlight	weakened, cutting down how far you can see
Mouse speed	increased, leaving you less time to react

Quick facts about the game

Summary

In short MOUSE is a fiction built on a public-domain cartoon and has no connection to Disney.

A few background details are worth knowing before you play, especially if you are curious about the setting or the game's origins.

Setting　a steamboat called the S.S. Willie that disappeared in 1928
Threat　an entity known only as the Mouse
Inspiration　the horror short film 'The Vanishing of S.S. Willie' by Night Signal Entertainment
Source material　the 1928 public-domain cartoon Steamboat Willie
Disney connection　none; the game is not affiliated with or endorsed by Disney

Glossary

S.S. Willie: The steamboat where the game takes place, which vanished in 1928 and serves as the entire escape environment.
The Mouse: The entity that hunts players aboard the ship and must be avoided to escape.
Crew: The other players in your session who are also trying to escape; relying on them disqualifies you from the Alone badge.
Hardcore mode: A special mode that restricts you to one life, removes hiding spots, weakens your flashlight, and speeds up the Mouse all at the same time.

Common questions

FAQ

Can I earn the Alone badge in a room with other players?

Yes. The badge only requires that you escape without crew assistance, not that you are literally the only person in the session. As long as you navigate and escape entirely on your own, the badge can unlock even if others are present.

What instantly fails an Untouched attempt?

Any contact from the Mouse ends it. The badge description states the Mouse must never lay a hand on you, so the moment you are caught — even once — that run no longer qualifies.
