This jam is the official companion to Mausritter Month (Nov 4 – Dec 4) — the community-wide celebration of all things sword-and-whiskers!
If you submitted to the BackerKit Mausritter Month event and didn’t get chosen — this jam is for you.
If you’re just discovering Mausritter and want to make something small, weird, cozy, grim, or glorious — this jam is for you.
If you just love mice with swords — well, this jam is definitely for you.
No theme. No competition. No prizes. Just pure fun, creative freedom, and community celebration!

Mausritter Month is a global collaboration between Losing Games, Games Omnivorous, Exalted Funeral, and an ever-growing community of third-party creators. It runs Nov 4 – Dec 4 2025, featuring new official projects, community spotlights, and the return of the Mausritter Core Box Set and The Estate Collection.
You can learn more and see the official releases (including JUNK CITY, the anchor project by Isaac Williams & André Novoa) through the Mausritter Month hub on BackerKit.

This Companion Jam runs Nov 11 – Dec 11 2025 — one week later — to give every mouse, mole, shrew, and frog in the community a chance to share their own creations!

Community Spaces
Can I submit something I’ve already made? Yes, but we’d prefer new things – this is a chance to grow and expand the community.
Can I collaborate with others? Absolutely! Team projects are encouraged.
Do I have to sell my work? Nope — free, PWYW, or paid are all welcome.
What languages are accepted? All! Mausritter is a global community — multilingual projects are wonderful.
Do I need to use a specific format or layout? No strict requirements.
What happens after the jam? All submissions will be featured together on a celebration live stream and promoted on social media. All submissions will be added to the Mausritter Library as well.
Who can I contact for help? Message Matt (ManaDawn / @manarampmatt) on Discord or email manarampmatt@gmail.com.
