Promised to ship before the movie so... 📅 53 days 🤖 731 vibe coded commits ⚡️ Powered by @threejs 🚀 Inspired by a space plumber 🙋‍♂️ AMA, no secrets, no shame High level, grouped list of what's in this game: Galaxy DNA - Lumas - Star Bits - Spin attack with air boost + ground-cancel - Galaxy gravity - Octoombas - Gateway Galaxy music track Vibe Coding Process - Claude Code (Opus) for ~95% of all code - CLAUDE.md project instructions file (163 lines of rules + constraints) - 87 implementation plans written before coding - 36 AI code reviews (ECS, architecture, performance) - 11 retrospectives after major features - 60 extracted skills (reusable knowledge from debugging sessions) - Constraints doc that grows every time something breaks (115 lines) - /lets-build workflow: discovery → plan → review → implement → verify - Every feature: plan first, review the plan, then build in atomic commits - Custom level construction CLI (AI-assisted placement) - this evolved over 53 days Architecture - Custom ECS engine (Structure-of-Arrays, zero-alloc hot paths) - Benchmarks faster than bitECS on packed iteration - 117 ECS systems orchestrated in explicit update order - Data-oriented Process system (sequential/parallel composition) - 30+ process types: UI animations, camera arcs, sfx Rendering - Three.js + Pixi.js sharing one WebGL2 context - Three renders 3D, Pixi renders UI — no extra canvases - Half-res bloom, color grading, occlusion silhouettes - Fresnel rim lighting + hemisphere ambient for Galaxy-style polish Physics - Rapier3D WASM physics (SIMD build) - Kinematic character controllers for player + all enemies Gravity - Galaxy-style gravity fields (walk around surfaces) - 4 gravity field types - Priority-based gravity resolution with distance tiebreakers - Convex hull letter platforms with per-face gravity - Spring-damped gravity transitions Shadows - Multi-pass gravity-aware shadow system - Per-instance shadow filtering via vertex shader attributes - InstancedMesh candidates promoted across gravity fields - Dynamic frustum sized from camera FOV each frame Camera - camera system with 12 critically damped springs - Follow-gravity mode (trailing orbit in tangent plane) - Fixed-up mode (screen stays level on letter platforms) - Top-down mode (Galaxy overhead cam, roll-free quaternion) - Camera collision via 4-direction spherecast repulsion - Override blend system for boss fights + pipe travel - Catmull-Rom spline intro flythrough with per-waypoint duration Space - Procedural space nebula (simplex noise shader, 3 octaves) - 1,800 seeded stars with per-star brightness + color variety - Galaxy-authentic palette across all screens Enemies - 5 enemy types with full AI state machines - Goomba, Koopa, Spiny, Bob-omb, Octoomba - 3D distance → FOV cone → LOS raycast detection pipeline - Editor-placed OBB avoidance zones with deflection hysteresis - Recoil, stun, shell, fuse, and ranged attack behaviors Boss Fight - Bowser Jr. boss fight - Multi-phase combat with Bob-omb spawning - Controlled intro/outro sequence Mario - Galaxy-style spin attack - Rainbow diamond particle burst (InstancedMesh, 64 pool) - Hit-stop with global time scale freeze + camera shake - Air boost, ground-cancel, shell kick at extended range - Invulnerability frames during active spin Yoshi - mount/ride system with shield HP - +3 extra HP ring on mount, damage depletes shield first - Overflow damage carries to Mario - Forced dismount on shield break with poof effect Objects - Coin system with InstancedMesh rendering (256 max) - Per-instance opacity via shader patching - Pop → float → shrink → fade collection animation - Swap-and-pop O(1) entity removal - Star bit burst spawning with attraction system - Pipe warp travel with camera override blend - Parallel-transported screen-right vector during crossfade - Shadow field updates for traveling entities - trampoline - 3D assets from Hello Mario Framework (now archived) and game rips Audio - 17+ wired sound effects with spatial audio - Bob-omb fuse sound: per-entity lifecycle, looping playback tracking - Distance-based volume for poof and explosion effects UI - Odyssey-style ring HP meter with shield inner ring - Number roll + arc lerp stagger on health changes - Gold coin counter HUD - Loading screen with code-split fast first paint - Pretext layout flow in "legal" screen with retro Mario Controls - Mobile touch controls: virtual joystick + A/B buttons - Proportional analog stick with walk/run speed switching - Gamepad support: Xbox, PlayStation, Switch Pro - Dead zones, auto-reconnect, synthetic DOM key bridge Dev Tooling - experimental CLI level construction tool with undo history - 18 placement types with type-safe defaults - Atomic file writes, auto-backup (max 20), live reload - Dev server auto-save plugin for visual editor - Two-panel debug editor (Tweakpane) - Hierarchy + inspector with gravity field live editing - Translation/rotation gizmos with gravity-relative local space - Per-waypoint camera preview for intro spline tuning 731 commits. 53 days. 95%+ vibe coded.
