The ultimate multi-layer building game! Build across 4 vertical layers:
🏔️ Underground — Mine minerals and extract resources
🏠 Surface — Houses, farms, smelters. Food and processing.
☁️ Sky — Windmills and floating research labs
🚀 Space — Satellites and space stations for advanced research
Click buildings to construct them. Complete quests to unlock new layers and tech levels. Use Process All to gather resources from all your buildings. Score = total buildings across all layers × tech level.
