Retro Space Shooter VFX Sprite Sheet

Objective: To create a clean, white background atlas for a vertically scrolling, retro pixel-art space shooter game, showcasing individual bullet patterns, explosions, loot, asteroids, and particle effects while maintaining a consistent 2D pixel art style. Canvas: 1:1 square sprite atlas, approximately 768×768 pixels, pure white background, no grid, no labels, no borders; assets are evenly distributed in horizontal rows, with transparent blank areas around each asset. Visual Style: High-resolution retro pixel art with sharp edges, neon lighting effects, saturated colors, arcade shooter VFX style, using black or dark outlines only where necessary, with additive glowing halos, and no text. Color Palette: Using three primary energy colors:{argument name="cyan energy color" default="Electric Blue"} ,{argument name="purple energy color" default="Violet"} and{argument name="green energy color" default="Bright lemon green"} In addition, there's orange/yellow for explosions and grayish-brown for asteroids. Layout and Precise Material Quantity: 103 visible sprites arranged in 8 rows. Row 1: 17 cyan player-shooting sprites, including micro bullets, small teardrop bullets, medium diamond bullets, paired vertical bullets, triple clusters, fragmentation volleys, three narrow exclamation mark bullets, two long laser beams, one large glowing missile-shaped spear, and two cyan starburst impact flashes. Row 2: 16 purple enemy-shooting sprites, including small round bullets, large spheres, thin diamond bullets, paired bullets, triple clusters, fragmentation clusters, three vertical capsule bullets, three single vertical bullets, and two purple starburst impacts. Row 3: 16 green enemy-shooting sprites matching the purple row type: small diamond bullets, large diamond bullets, bright spear bullets, paired bullets, triple clusters, fragmentation clusters, three capsule bullets, three single vertical bullets, and two green starburst impacts. Row 4: 15 Special Energy Sprites: Three circular neon spheres in cyan, purple, and green; three cracked plasma spheres in cyan, purple, and green; three vertical ground-striking laser beams in cyan, purple, and green (with splash bases); one solid cyan vertical beam; and three ring-shaped water droplet portal effects in cyan, purple, and green. Row 5: 9 Explosion and Impact Sprites: Five orange flame explosions of varying sizes, followed by four purple electric shock bursts of varying sizes, ending with a small diamond-shaped flash. Row 6: 10 Game Objects and Bullet Barrages: A green life-collecting icon with a white plus sign, a green mechanical enhancement module, a dark spiked mine, four orange arrow/fireball bullet frames pointing to the right, and three purple tracking/particle bullet clusters. Row 7: 10 Asteroid/Fragment Sprites: Six rocky asteroids ranging from large to pebble-sized, followed by four clusters of broken rock fragments. Line 8: 10 Particle Flash Clusters: two cyan flash clusters, two purple flash clusters, two green flash clusters, two orange flash clusters, and two sparse orange trailing flash clusters. Main Details: Ensure the bullet hell is clearly identifiable as an independent game sprite, with each sprite centered within its empty area. Energy bullets should be symmetrical, vertically oriented where appropriate, and have a soft halo. Explosions should use a layered yellow core, orange petals, red outline, and scattered sparks. Asteroids should be irregular dark rock shapes with pixel highlights and shadows. Pickups should be more prominent and icon-like than the bullet hell. Constraints: Generate only sprite atlas assets, not game screenshots. No background scenes, no UI, no characters, no spaceships, no typography, no watermarks. Keep each asset independent and ready to be directly cut into tiles or sprites.
