🐀 Welcome to Rat Jam 2025! 🎉

Ah yes, Rat Jam—that time of year when otherwise respectable professionals suddenly decide that sleeping, eating, and general hygiene are optional, all in the noble pursuit of making a video game in far too little time.

For one weekend, our beloved office will transform into a realm of unbridled creativity, questionable design choices, and an ever-growing pile of empty cans. Game developers, artists, QA testers, and designers will band together in what can only be described as a magnificent act of collective madness.

Is there a colleague you don’t despise enough yet? Perfect! This is your chance to bond over bizarre bugs and a rapidly collapsing deadline.

🎭 Theme

The theme will be selected through a highly sophisticated democratic process, also known as voting—a tradition in which everyone enthusiastically participates before promptly blaming the outcome on everyone else.

[The winning theme will be announced in the office before the event starts.]

We’re sure you’ll take this simple idea and twist it into something deeply profound, wildly entertaining, or at the very least, playable.

🎮 Game Engine

Use any game engine you like. Unity, Godot, Unreal, your own home-brewed monstrosity held together by duct tape and misplaced optimism—we don’t judge.

🕑 Timeline

🗓 From: 26.6.2025 18:00
🗓 To: 28.6.2025 18:00

Which, for those unfamiliar with the concept of time, is precisely 48 hours—or just enough to go from “This is a great idea” to “Who thought this was a great idea?”

📥 Submissions

All teams must submit their final build before the event ends. No sneaky last-minute edits unless you can convince us that your game now contains fewer catastrophic failures than it did before.

🏆 Voting

Once the jam is over and the caffeine wears off, it will be time to judge what we’ve all created. Every participant will get a chance to play, rate, and question their life choices as they vote on each game based on the following criteria:

🔹 Creativity – Did the game take the theme and do something unexpected with it?
🔹 Gameplay – Is it enjoyable, or did it just make people cry (for the wrong reasons)?
🔹 Art – Does it have a unique style, or just sentient placeholder assets?
🔹 Theme– Does it cleverly embrace the theme, or was it added as an afterthought?

Each participant (submitter and contributor) will rate the games, and once the votes are in, we will crown the champion—a prestigious title that comes with eternal bragging rights and possibly a piece of cheese.

🚀 Are You Ready?

This is your moment! Sharpen your wits, stretch your fingers, and prepare for two days of coding, designing, and slowly losing your grip on reality.

Good luck, have fun, and may your game at least compile! 🐀🎮
