- 20 real elements from periodic table (H through Hg) with accurate data - 25 compounds with game effects (NaCl, H₂O, gunpowder, thermite, etc.) - 34 reactions: synthesis, combustion, acid-base, redox, decomposition - Reaction engine with O(1) lookup by sorted reactant key - Educational failure reasons (noble gas, missing heat/catalyst, wrong proportions) - Condition system: temperature, catalyst, energy requirements - 35 unit tests passing, TypeScript strict, zero errors Co-authored-by: Cursor <cursoragent@cursor.com>

Synthesis — Development Progress
Last updated: 2026-02-12
Current phase: Phase 1 ✅ → Ready for Phase 2
Completed
Phase 0: Project Setup ✅
- Game Design Document (
synthesis-gdd.md) - Engine analysis and tech stack selection (
engine-analysis.md) - npm project + dependencies (Phaser 3, bitECS, TypeScript, Vite, Vitest)
- TypeScript strict config
- Vite config (HMR, chunk splitting)
- Phaser config (1280x720, pixel-art, arcade physics, top-down)
- BootScene with title screen
- Cursor rules (6 rules: project context, agent workflow, ECS, chemistry, Phaser, data)
- Implementation plan (
IMPLEMENTATION-PLAN.md) - Progress tracking (this file)
Phase 1: Chemistry Engine ✅
- 1.1 Types and interfaces (
src/chemistry/types.ts) - 1.2 Element data — 20 real elements (
src/data/elements.json) - 1.3 Element registry with lookup by symbol/number (
src/chemistry/elements.ts) - 1.4 Reaction engine — O(1) lookup, condition checking, failure reasons (
src/chemistry/engine.ts) - 1.5 Reaction data — 34 real reactions (
src/data/reactions.json) - 1.6 Compound data — 25 compounds with game effects (
src/data/compounds.json) - 1.7 Unit tests — 35 passing (
tests/chemistry.test.ts)
In Progress
None — ready to begin Phase 2
Up Next: Phase 2 — ECS Foundation
- 2.1 World setup (bitECS world + time tracking)
- 2.2 Core components (Position, Velocity, SpriteRef, Health)
- 2.3 Movement system
- 2.4 Phaser ↔ bitECS sync bridge
- 2.5 Entity factory
- 2.6 Health/damage system
- 2.7 Visual test (entities moving on screen)
