**KSEF — A Windows XP Bureaucracy Simulator**
You are **Janusz Kowalski**, a 47-year-old small business owner from Radom, Poland. Your mission? Issue one single e-invoice through KSeF — the Polish government's new electronic invoicing system. How hard can it be?
**Very.**
Between crashed logins, cryptic error codes, your wife's increasingly angry messages, and a system that seems designed to break your spirit — you have until 5 PM to get it done. Or lose everything.

### FEATURES
- **Full Windows XP desktop simulation** — taskbar, Start menu, draggable windows, desktop icons, and the iconic Bliss wallpaper. It looks and feels like 2003.
- **15 interactive apps** — KSeF invoice system, email client, GaduGadu messenger, Internet Explorer with 10 parody websites, Minesweeper, Solitaire, Notepad, Calculator, file browser, music player with disco polo tracks, coffee machine, phone, printer, helpline, and a trash can.
- **Stress, Patience & Money systems** — every action has consequences. Drink coffee to calm down (but it costs money). Browse the internet (but you're wasting time). Call the helpline (47-minute wait).
- **30+ random interruptions** — Windows Update popups, telemarketer calls, your neighbor knocking, your son asking for Robux, ZUS demanding documents, and more.
- **Spinaczek (Clippy)** — your sarcastic office assistant with 60+ context-sensitive comments and mood-reactive animations.
- **Microphone detection** — yell at your screen and Janusz's stress goes up. The game is listening.
- **5-act story structure** — login, fill the invoice, handle a correction, survive a tax audit, and submit the final report. Each step more absurd than the last.
- **Multiple endings** — emigrate to Germany, achieve Zen enlightenment, rage quit, blue-screen, or actually succeed (with varying reactions based on your stress level).
- **70+ achievements** — from speedrunning the invoice to discovering every file on the computer.
- **4 disco polo tracks** in a fully functional Winamp player.
- **All dialogue and content in Polish** — an authentic Polish experience with real bureaucratic terminology, parody brands (JuTjub, Gugle, Alledrogo, Wykopki), and dark humor.
**Playtime:** 45–60 minutes per run.
