IDLE Game
Post-apocalyptic base builder with robot units
Overview
A Fallout Shelter-inspired idle game built with HTML5 Canvas. Excavate underground chambers, manage resources, deploy robot units, and survive procedural events in a post-apocalyptic world.
Core mechanics
- 2D grid excavation - dig downward to reveal resources and expand your base
- Robot units - assign workers to mining, construction, and defense
- Resource management - balance energy, materials, and food
- Procedural events - random encounters that challenge your survival strategy
Design philosophy
Every system feeds back into every other system. Energy powers robots, robots mine resources, resources build infrastructure, infrastructure generates energy. The loop is the game.
How it evolved
Started as pure idle mechanics - click to dig, wait for resources. But idle-only felt hollow. Adding real-time strategy elements (robot deployment, defense planning) created the tension that idle games need: you care about what happens while you’re away because you built something intentional before leaving.
The offline progression was the hardest design problem. Full-speed simulation while offline makes the game feel like it doesn’t need you. The solution: 1/3 speed offline. Your base still runs, still produces, but slowly. Coming back feels like checking on a garden, not opening a finished product.
Next: procedural events that create genuine dilemmas - evacuate a section and lose resources, or defend it and risk your robots.
