Let Rat Be Demo

Description

Follow the tiny mouse’s footsteps and explore a strange world built on top of your keyboard.

This is a casual puzzle game where you press multiple keys at the same time to create paths, jump, and land.

What begins with simple inputs gradually evolves into increasingly complex challenges, 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 built around multiple simultaneous key inputs

Stages that test your finger positioning, timing, and input sequence

A gameplay experience where the keyboard itself becomes part of the puzzle

A strange and charming miniature world unfolding across your keyboard

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.

Please also note that certain international keyboard layouts (such as AZERTY, QWERTZ, or other non-standard regional layouts) may not fully support all required key positions used in the game.

About This Demo

This demo allows players to experience Chapters 1–3 of the game. For the full release,
I plan to add 2–3 additional chapters featuring new gameplay mechanics and further improve the game's visual assets. Your feedback on this demo will be a great help in improving the overall quality of the game.
