Solar

What I saw: Renders cleanly with all 8 planets, elliptical orbit rings, glowing sun, Saturn's ring, and a polished title/legend UI; log-scaled distances plus interactive orbit/zoom controls are a thoughtful touch. Weaknesses are flat-colored planets (no textures) and inner planets crowding the sun, keeping it strong-shippable rather than field-topping.

What I saw: Fugu Ultra v2 rebuild — 55.7KB solar system, the densest solar attempt on the bench. Full </html>, animation loop, Saturn rings, drag-to-orbit + scroll-to-zoom. Smoke-test PASS (3.6% pixel diff after drag, zero console errors). The panel ensemble produces a markedly richer build than Mini's 12KB single-model version.

What I saw: Single-model Fugu Mini shipped a complete 12KB solar system in 3.5 min — full </html>, animation loop, Saturn rings, drag/orbit. Verified PASS by headless-Chrome smoke test (pixel-change + no console errors after click + WASD).

What I saw: Most polished solar attempt I've graded — glass-morphism control panel with time slider, sun-glow slider, orbits/labels/pause toggles, hover info cards on every planet, Saturn's rings, accurate moons. Drag-to-orbit + scroll-to-zoom. Beats Opus on UI density without losing the physics.

What I saw: Strong 3D Three.js render with a beautifully textured sun, visible orbital rings, detailed planets, and a clean glassmorphism UI with accurate per-planet data cards, speed controls, and a full nav bar. Slightly held back by the sun looking overly mottled/scaled and no visible orbital labels, but overall shippable and near the top of the field.

What I saw: Three genuinely good space sims. Opus tilts the orbits into real 3D with a bloom-heavy sun and Saturn's rings. GLM's is the most product-like — labelled planets, orbit and label toggles, a clean HUD. Kimi's is a tidy tilted-orbit system with rings and a deep starfield. Opus and GLM are neck-and-neck; Opus takes it on the 3D feel.

What I saw: Strong 3D render with glowing sun, distinct textured planets, asteroid belt, tilted Keplerian orbits, and a polished glass UI with live date/speed and info panel — clearly on-brief and shippable. Minor nit: labels crowd near the inner planets, but overall it beats the field's best.

What I saw: Solar system on canvas with orbits + Saturn rings + moons. 12KB — compact build, drag-to-orbit + scroll-to-zoom. Slightly less polish than Fusion's glass UI version.

What I saw: Renders cleanly with polished typography, orbit rings, starfield and interactive controls, but the camera framing is broken — the Sun sits off-center, planets aren't clearly the largest bodies, no Saturn rings, and the scale/order reads as a generic sphere scatter rather than an accurate, legible solar system.
