About this game

You are a plush teddy bear — soft, cute… and completely unprepared for what lies ahead. Arriving at a mysterious hotel in the middle of Nowhere with your little suitcase, you quickly realize — something here is… off.

Behind every door awaits a new absurdity: a chemistry lab with sudden explosions, a boxing ring with no rules, a noisy party full of rubber ducks, and at the end of the corridor — a mysterious door leading into a dark underground…

Explore the rooms, interact with this bizarre world, and watch as the strange hotel slowly descends into madness — along with you.

This is a game of cheerful nonsense, where logic has long since checked out, and common sense never checked in.
