About this game
It’s a wide world out there. A brave mouse can’t do much but hold on and pay attention—but sometimes just paying attention is enough.
Every landscape has a story, and it’s your job to tell it. BRAVE MOUSE CARTOGRAPHER is a series of ambient systems designed to serve as the jumping off points for player expression. As sections of the map are revealed, players can translate findings as drawings onto whatever medium they like outside of the game — paper, drawing software, wet cement, crop circles — whatever you like!
- At your own pace — The bird waits for no one, so the pressure is off! Tune in and out at your leisure, engaging as much or as little at any given moment as you feel like.
- Lush generative soundscapes — Carefully handcrafted loops fading in and out at the whims of random movement make for a constantly fresh and surprising aural experience.
- Express yourself — No two eyes see the world the same way; the map you make of the world you see reflects your self as much as it does your environment. Compare yours with your friends, or combine them and see what you get!
- The more the merrier — The perfect low-stakes cooperative game for a group of any size, from an intimate stream to a bustling festival to any sized party in between.
Witness the triumphant return of the BRAVE MOUSE CARTOGRAPHER franchise in this definitive special collection edition!
Featuring music by KARL HOHN
