January's Challenge is there!

Bonne Année ~ Happy New Year!

As promised, here's your first 2026 present: A new challenge!

January Challenge: Tall Tower

🗼 All rooms are stacked to form a 12-stories tower.

📌 You start on the bottom, with the push pins, and the exit is on the top of the tower.

🗝️ There are 5 locks, but 7 keys are hidden in the tower, so you won't need to open as many checks as usual.

Vote for February's Challenge!

Join the Discord server to vote for the next one. Here are the choices:

🎉 Party Apartment - Most of the mice are in a small 1-stage apartment of 4-5 rooms.

🪙 Cash Castle - Presents and quests only give coins. All the useful items are in Gacha Machines.

👻 Ghostly Gathering - All presents & NPCs are invisible, and of course they're shuffled.

Let's race!

I'd like to organize some races on the Tall Tower and Full House challenges. If you're interested, it'll be organized in the Discord as well.
