Multiplayer Action Web Game

I want to bring a fast-paced action game to the browser that players can jump into together, whether they open it on a phone or a desktop monitor. The single most important feature is real-time multiplayer: matchmaking, in-game chat (text is enough for now), and smooth synchronisation so latency never spoils the fun. The build needs to adapt gracefully to desktop and mobile screens without forcing users to install anything. A modern HTML5/WebGL front-end paired with a lightweight Node.js, Phoenix, or similar real-time back-end is fine—as long as the final result is secure, performant, and easy for me to deploy on a standard cloud host. I’m open to adding leaderboards or character customisation later, but they are not in scope for this first milestone; the goal is to nail the core multiplayer action and cross-platform play first. Deliverables I’ll use to sign off the job: • A playable browser build demonstrating the core gameplay loop with at least two players connected simultaneously • Complete, well-commented source code (front-end and back-end) pushed to a private Git repository I provide • A short README covering setup, build commands, and deployment steps for both development and production environments • One round of bug-fixes after I test the initial delivery on both mobile and desktop browsers If you have questions about mechanics, art style, or suggested tech stacks, let me know early so we can lock them down and keep the schedule tight.
