You wake up at your desk in the office, as you have many times before. The computer hums to life and displays the usual orders. Break The Codes. Use Your Notes. Free Yourself. The 5-minute timer starts to Count Down.

Will today be the day you finish the job and get to clock out? Or will you be in for more Overtime?

In Overtime, you will need to solve a series of increasingly difficult ciphers in the given time and earn your right to leave work. Good luck!

I'm a space physicist and part-time solo developer working with my fiancé who is an artist and designer. Everything in the project was made during the duration of GMTK Game Jam 2026. The game was made in Unity, pixel art was made using Aseprite, and sound effects were made with Chiptone.

I hope you enjoy!

Solutions to decode the ciphers will be available after the jam!
