Desk Cat Coder
Desk Cat Coder is a free browser stealth platformer you play without an account or install. You are a cat sneaking lines of code onto the office computer while the owner is away - climb the desk, type while the coast is clear, and ship seven days of work.
How to play
- Press Play to load the ~72 KB canvas engine in a same-origin iframe, then click Start Game on the title screen.
- Use Arrow Left and Arrow Right to move and Arrow Up to jump between desk shelves as you climb to the computer.
- Reach the computer while the owner is away and spam letter keys to add lines - each keypress adds to the day's total.
- If the owner is sitting at the PC and you stay in view, they slowly undo the lines you shipped, so keep out of sight until the coast is clear.
- Push drinks, food, or other desk objects with the arrow keys to distract the owner and buy more typing time.
- Keyboard is required to play; there are no touch controls.
The seven-day campaign
Play runs across seven work days. Each day ends with a score screen and a Next Day prompt, and the daily totals fill a git-style contribution grid. Your rank reflects the total lines shipped across the week. An optional fedora checkbox on the title screen is cosmetic only and does not change how the game plays.
Privacy and what runs on your device
Nothing leaves this device except the initial page and the game files served from this site: the whole game runs in your browser, with no server backend, no runtime fetch, and no score saved between sessions. Desk Cat Coder is adapted from the open-source BlackCat_Hacker (MIT, JS13K 2025) and ships its LICENSE and CREDITS with the page.
