Retro Space Shooter VFX Sprite Sheet — AI Image Prompt

Goal: Create a clean white-background production asset sheet for a vertical retro pixel-art space shooter, showing separate glowing projectile, explosion, pickup, asteroid, and particle-effect sprites in a consistent 2D pixel-art style.

Canvas: Square 1:1 sprite sheet, about 768×768 px, pure white background, no grid, no labels, no borders, sprites evenly spaced in horizontal rows with transparent-looking whitespace around each asset.

Visual style: High-resolution retro pixel art with crisp edges, neon glow, saturated colors, arcade shoot’em-up VFX, black or dark outlines only where needed, additive bloom-like halos, no text.

Color palette: Use three main energy colors: {argument name="cyan energy color" default="electric cyan"}, {argument name="purple energy color" default="magenta violet"}, and {argument name="green energy color" default="lime green"}, plus orange/yellow fire for explosions and gray-brown rocks for asteroids.

Layout and exact asset count: Arrange exactly 103 visible sprites in 8 rows. Row 1: 17 cyan player-shot sprites, including tiny bullets, small teardrop shots, medium diamonds, paired vertical bolts, triple clusters, grouped shard volleys, three narrow exclamation-like bolts, two long laser beams, one large missile-like glowing spear, and two cyan starburst impact flashes. Row 2: 16 purple enemy-shot sprites, including small round bullets, larger orbs, a thin diamond bolt, paired bolts, triple grouped bolts, clustered shards, three vertical capsules, three single vertical bolts, and two purple starburst impacts. Row 3: 16 green enemy-shot sprites matching the purple row types: small diamonds, larger diamonds, a bright spear bolt, paired bolts, triple grouped bolts, clustered shards, three capsules, three single vertical bolts, and two green starburst impacts. Row 4: 15 special energy sprites: three circular neon orbs in cyan, purple, and green; three larger cracked plasma orbs in cyan, purple, and green; three vertical ground-strike laser columns in cyan, purple, and green with splashing bases; one solid cyan vertical beam; and three droplet-over-ring portal effects in cyan, purple, and green. Row 5: 9 explosion and impact sprites: five orange fire explosions decreasing from very large to tiny, followed by four purple electric impact bursts decreasing from medium to tiny plus a small diamond sparkle at the end. Row 6: 10 gameplay objects and small shots: one green health pickup icon with a white plus sign, one green mechanical power-up module, one dark spiked mine, four orange arrow/fireball projectile frames facing right, and three purple homing/particle projectile clusters. Row 7: 10 asteroid/debris sprites: six rocky asteroids decreasing from large to pebble size, followed by four broken debris clusters of scattered rock fragments. Row 8: 10 particle sparkle clusters: two cyan sparkle clusters, two purple sparkle clusters, two green sparkle clusters, two orange sparkle clusters, and two sparse orange trailing sparkle clusters.

Subject details: Make the projectiles readable as individual game sprites, each centered in its own whitespace area. Energy bullets should be symmetrical, vertically oriented where appropriate, and glow softly. Explosions should use layered yellow cores, orange petals, red outlines, and scattered sparks. Asteroids should be irregular dark rock forms with pixel highlights and shadows. Pickups should be bolder and more icon-like than projectiles.

Constraints: Generate only the sprite sheet assets, not a gameplay screenshot. No background scene, no UI, no characters, no ships, no typography, no watermark. Keep every asset isolated and production-ready for cutting into tiles or sprites.39:
