We make productivity tools. Privacy-focused email, PDF annotation, health tracking — serious stuff. So naturally, we made a traffic light game.
Tuesdae Rush is a fast-paced intersection sim where you tap to switch signals and try to keep cars flowing before gridlock takes over. It's simple, it's addictive, and it was our first time building a game.
Why a Game?
Honestly — because it sounded fun. We spend most of our time thinking about encryption, local-first architecture, and accessibility compliance. Sometimes you just want to build something where the only goal is "don't crash the cars."
It also turned out to be a great exercise. Games push you to think about performance, timing, and feedback loops in ways that utility apps don't. Every millisecond matters when cars are piling up.
Built with Flutter
We used Flutter for everything else, so it made sense here too. The rendering pipeline handles smooth animations natively, and we got web, mobile, and desktop support from a single codebase. No game engine, no complex setup — just Flutter's canvas and a lot of tweaking.
The whole thing runs at 60fps with minimal overhead. Turns out the same CustomPainter skills from building Cristalyse translate pretty well to drawing cars and intersections.
Open Source, Obviously
We open-sourced it. Felt wrong not to. If someone wants to poke around the code, learn from it, or build their own version — that's exactly the kind of thing we'd want to encourage. The source is on GitHub.
