Ken is a game developer. His team has made a new game about a flying fox. Tomorrow, it will go online.

At midnight, Ken finds a bug. The fox can fly through walls. He is patient and tries to find the cause.

He is diligent. He tests the same level ten times. He reads the code line by line.

At 3 a.m., he finds it: one wrong number. He changes it. The fox stays inside the walls.

Ken is good at this work, but he is tired. He saves the game and goes home.

The next day, children play the game and laugh. Ken is proud of the team. No one sees the bug, but he knows it is gone.

A thought to keep

A small bug can hide a big lesson.
