Pacman-inspired promotional game paired with a custom Electron tool enabling marketing teams to reskin the game without rebuilding Unity.

• Developed the game in Unity and deployed it as a Telegram-compatible WebGL experience.
• Built an Electron + Node.js desktop tool allowing non-technical staff to update sprites and branding without a new Unity build.
• Implemented automatic image processing (resizing, format checks, previews) to reduce configuration errors.
• Created backend logic and SQL storage for runtime asset loading, enabling multiple campaigns from a single WebGL build.
• Handled deployments and collaborated on NGINX configuration to ensure stable asset delivery.
