Design an original games app icon with a green palette, using the attached icon as a visual reference for its style, palette and composition. Create a clear composition with a single strong focal shape and confident color. Make the subject a bold, dimensional emerald-green game controller with simple luminous buttons, centered and prominent. Draw inspiration from the reference's vibrant green field, bright highlights, soft glow, and playful glossy dimensional rendering, but make a distinctly new design: no soccer ball, player silhouette, or surrounding stars.
