Blinking 'PRESS START' Text on Dungeon Door

"Keep the original image 100% unchanged. Overlay a blinking 'PRESS START' text in retro console arcade style. The text should be pixelated, blocky, and match the image's color palette. Blink slowly (1 sec on, 0.5 sec off) near bottom center. Do not animate or alter the original background or objects. Output as looped GIF."
