Use case: ui-mockup
Asset type: single concept screenshot for Space Attack, a polished browser arcade shooter.
Primary request: Create ONE wide landscape 16:9 screenshot of live gameplay, not a collage, a poster, or a photograph of a screen. It must look straightforward to recreate using vanilla Canvas 2D polygons, rectangles, strokes, gradients, shadowBlur, and small code-generated particles.
Style reference DNA: Geometry Dash screenshot with a vivid violet playfield #4E1ED6, giant darker purple inset rectangular wall panels #33148C and #3C17A5, lime main character #93F041 with heavy black outlines and a cyan #0AFBFC inset, mint accents #C7FFCD, near-white #FFF7FF glowing hazard outlines. Clean elementary geometry, flat saturated fills, restrained soft violet-white glow. Match this playful bright purple geometric style closely.
Composition: gameplay arena fills the image, a narrow HUD strip at top and narrow status strip at bottom. Large empty space for readable action. Background is layered oversized recessed purple rectangles with subtle borders, a simple vertical gradient and sparse tiny square particles. No realistic space imagery.
Top HUD: left 'SCORE 02480', center small 'SPACE ATTACK' with smaller 'WAVE 03' beneath, right 'HIGH SCORE 08640'. Compact bold square geometric arcade typography, legible white with subtle violet glow. Small 'DEBUG F3' and 'DASHBOARD' buttons near upper right below the high score.
Enemies: a tidy evenly spaced formation of about 18 small distinct angular enemies in three rows high in the arena. Each is a simple dark almost-black geometric silhouette with sharp near-white glowing outlines, lime or cyan square cores. Visually lightweight compared with the player. ONE enemy peeled off the formation and diving in the middle-right of the arena, tilted down toward the player, with a short fading zigzag trail of mint square particles and angular line segments. A visible gap marks its original formation slot.
Player: unmistakable lime-green upward-pointing triangular spacecraft near the lower center-left, thick near-black outline, simple cyan square inset cockpit, two small angular wings, and short mint square-particle thruster trail. Exactly one player ship. Two slim upward cyan laser bolts above it. A few sparse pale enemy bullets aimed diagonally into the open arena.
Bottom HUD: on left the text 'BOOST ENERGY' over a rectangular meter filled about 70 percent in cyan/mint, bright thin outline and darker empty remainder. On right 'LIVES' followed by three small lime ship icons. Small centered controls text 'WASD / ARROWS  MOVE     SPACE  FIRE     SHIFT  BOOST'.
Motion feel: precise, energetic, rhythmic arcade action, crisp angular trails and isolated square particles; no massive explosions. Keep hazards, bullets, player and HUD clearly separated.
Constraints: a finished coherent gameplay screenshot. All art drawable with simple Canvas 2D shapes and modest glow. No photographic textures, no 3D bevels, no painterly details, no complex mechanical spaceship rendering, no horizontal platformer ground or spikes, no extra UI panels, no browser chrome, no watermark. This is a new game concept using the described style, not a copy of the reference level.
