Project Journey
Maths anxiety in students is real — but gamification can flip that dynamic entirely. Calculator Rush was built to make speed arithmetic feel genuinely fun and competitive rather than like homework.
The 'Rush' feel required sub-16ms input response — any perceptible lag kills the competitive tension. Significant time was spent optimising the state management layer to keep every frame budget tight during peak gameplay.
Achieving sub-16ms input latency for a truly 'fast' feel, syncing leaderboards reliably with offline-first gameplay, and building an adaptive difficulty engine that scales well without feeling unfair.
Currently in closed testing with a small group of student testers. Launching publicly soon.
