Star Hauler Command

A no-build 2D planet resource-gathering game built with Canvas 2D and ES modules.

Run

1. Open index.html directly in desktop Chrome or iPhone Safari.
2. Optional: serve locally for cleaner module loading behavior (python3 -m http.server).

Gameplay loop

• Planets continuously produce mixed resource profiles into local buffers.
• Ships cycle through: TRAVEL_TO_PLANET -> LOADING -> TRAVEL_TO_MOTHERSHIP -> UNLOADING.
• Expand to new planets to unlock new resource types, establish colonies, and develop industries.
• Colony industries generate Science, which unlocks advanced technologies.

Balance notes (current)

• Starter planet now outputs a guaranteed mixed profile (Ore/Energy/Water/Bio), so the early game can fund ship growth and first expansion without soft-locking.
• Early planet unlock costs are reduced and weighted toward accessible resources.
• Early economy tuning: higher base extraction, slightly better starting stockpile, and stronger starter ships.
• Cost formulas for ships/extractors/colonies are centralized in simulation logic to keep UI prices and gameplay prices consistent.

Controls

• Desktop: drag to pan, mouse wheel to zoom, click ships/planets to inspect.
• Mobile: drag to pan, pinch to zoom, tap to select; bottom tabs switch Actions/Details/Tech.

Features

• 10 resources with progressive unlocks (Ore, Water, Bio, Energy, Silicon, Crystals, Reactive Gas, Alloys, Antimatter, Science).
• 20-planet star system with distinct planet archetypes and scalable unlock costs.
• Colony system with industry development (Mining, Refining, Biolab, Fusion Plant, Research Nexus).
• Expanded technology tree that depends on colony-driven Science generation.
• Curved ship paths + thruster trail + cargo indicator + floating unload text.
• Fixed-step simulation (10 ticks/s) + smooth render loop.
• Save/load in localStorage, offline progress capped to 8 hours.
• Reset save from DevTools: resetSave().
