About the Project We’re enhancing an existing Unity-based multiplayer Rummy game for mobile web browsers. The goal is to deliver a smooth, native-like mobile experience with precise touch interactions, seamless payments, and essential security hardening. No game logic changes are needed—focus is purely on UI/UX refinement, wallet/payments, and security hardening. We’re looking for a Unity developer who understands mobile web performance, touch-driven interfaces, and secure integration workflows. Your Mission Optimize and polish the existing Unity WebGL build to deliver: Flawless mobile-first UX – especially for iOS Safari/Chrome and Android Chrome. Smooth drag-and-drop, snapping, scaling, and board interactions matching a reference Rummy app. Points wallet + Tranzila payment integration (one-time purchases). Session management (one session per user, auto-logout). Basic security hardening for a production environment. Responsibilities: Mobile UI/UX Optimization Fix card scaling, board resizing, UI overlaps, touch precision, and drag-and-drop behavior on mobile browsers. Ensure smooth card movement, snapping, board scaling, and visual feedback. Match the interaction quality and “game feel” of a reference Rummy app (provided). Payment & Wallet System Implement a points wallet system tied to user accounts. Integrate Tranzila payment gateway for one-time points purchases. Ensure automatic wallet credit and transaction recording. Session & Security Implement one-active-session-per-user logic. Add auto-logout after inactivity. Apply basic security hardening: input validation, session protection, API authorization. Performance & Compatibility Ensure smooth performance on mobile web (WebGL). Test across iPhone (Safari/Chrome) and Android (Chrome) browsers.
