About the game

One button, one sword, and a lot of nerve. Each click tries to raise your katana's level. Win and the blade gets stronger. Lose and it can break, taking your progress with it. Keep pushing for the highest level you can reach.

How to play

• Click the Upgrade button with the mouse to strengthen your katana.
• A successful upgrade raises its level, while a failed one can destroy the sword.
