Let Rat Be (Demo)
Description
Follow the tiny mouse’s footsteps and explore a strange world on top of your keyboard.
This is a casual puzzle game where you press multiple keys at once to create paths, jump, and land.
It starts with simple inputs, but gradually evolves into a challenge where finger positioning, timing, and key combinations become essential making the keyboard itself feel like a puzzle board.
Press all the keys shown on the screen to open the way and guide the little mouse to its destination.

Features
- A unique keyboard-based puzzle action system that uses multiple simultaneous key inputs
- Stages that test your finger positioning and input sequence

Important: Input Device Notice

This game is designed around pressing multiple keys simultaneously.
For the best experience, we recommend using a keyboard that supports NKRO (N-Key Rollover) or has strong multi-key input capabilities.
On some standard keyboards, pressing multiple keys at once may result in input errors or unintended input limitations.
If your inputs are not being recognized properly, please use the in-game ghosting test to check whether your keyboard can register at least 12 simultaneous key presses.
