Interface utilisateur de jeu de tir spatial rétro pixelisé

Create a premium vertical mobile game screenshot for a retro pixel-art space shooter, portrait 9:16. The image must look like an actual in-game scene, not a poster or asset sheet. Use crisp high-resolution pixel art with dense neon detail, black space background, purple nebula clouds, star field, scattered asteroids, and two visible planets near the lower left and lower right edges. Center the action vertically: at the bottom center is the player ship, a white, cyan, and gold angular fighter with three bright cyan engine flames and blue cockpit glass, firing a thick central stream of cyan laser bullets upward. At the top center is one enormous symmetrical boss battleship in purple, teal, dark gray, gold, and neon green, with wide wings, many armor panels, two large side cannons, glowing green core diamond in the middle, and blue exhaust trails beneath it. The scene shows intense bullet-hell combat: exactly 1 player ship, exactly 1 giant boss ship, exactly 4 smaller enemy fighters around the middle area, exactly 2 crescent-shaped drones near the upper left and upper right sides, exactly 2 round green shield drones near the mid-left and mid-right, exactly 1 orange explosion slightly left of center, exactly 1 green health pickup icon with a plus sign on the lower right, many cyan player shots rising in columns, and multiple purple and green enemy projectiles descending diagonally. Overlay a futuristic cyan and magenta pixel HUD with transparent dark panels and sharp sci-fi borders. Top left HUD: label “SHIELDS” with exactly 10 glowing blue hex shield icons, and below it a score panel reading “SCORE” and {argument name="score value" default="00547890"}. Top center HUD: label “TIMER” with a clock icon and {argument name="timer value" default="01:48"}. Top right HUD: label “BONUS TIMER” with a segmented magenta bar showing exactly 6 filled pink segments and 3 empty dark segments, and below it a “KILLS” panel with a purple alien skull icon and {argument name="kills value" default="235"}. Bottom left HUD: “WEAPON” panel with a cyan three-shot weapon icon and a small charge meter with exactly 4 filled cyan bars and 2 empty bars. Bottom center HUD: “OVERDRIVE” panel with exactly 10 filled orange bars and 8 empty dark bars. Bottom right HUD: “SMART BOMB” panel with a skull bomb icon and {argument name="smart bomb count" default="x03"}. Keep all UI text pixelated, legible, and aligned to the screen edges like a real mobile arcade game interface. Use vibrant cyan, violet, magenta, green, and orange glow effects, strong contrast, symmetrical composition, no watermark, no extra logos, no realistic 3D rendering, no blurred painterly style.
