Colour Champion — Cross-Platform Reflex Game
The Result
A polished, free-to-play game live on both app stores with online multiplayer, ranking and a competition layer that drives repeat play.
The Challenge
Colour Champion is a fast-paced colour-reaction game — easy to learn, hard to master — that tests focus and reflexes. The hard part is not the core loop; it is everything around it: low-latency real-time multiplayer and private rooms, fair matchmaking, global leaderboards, achievements and tournaments, all delivered smoothly on both iOS and Android from a single codebase.

Tech Stack
