Forge & Field

An idle RPG where idle time funds real strategic decisions

View LiveSource Code

Overview

A mobile-first PWA idle RPG that rejects clicker-style number inflation in favor of meaningful decisions: what to craft, which heroes to equip, where to send expeditions, and when to prestige. Runs entirely client-side — no backend, no accounts, no loading screens — with offline progress, versioned save migrations, and weekly rotating seasonal content.

Key Contributions

  • Single-reducer architecture with ~60 action types — deterministic state transitions make save/load and offline calculation trivial
  • Crafting and rarity system with weighted drops (Common 58%, Uncommon 25%, Rare 12%, Epic 5%) and stat-multiplied tiers
  • Deterministic turn-based combat engine: speed-sorted turns, cooldown-gated skills, party-wide auras, defense-penetration math
  • Multi-axis progression — player levels, hero skill evolution trees, village buildings, and prestige multipliers
  • Weekly rotating seasons (Harvest Festival, Iron Age, Golden Market) with exclusive recipes and resource boosts
  • Region-based world map with endurance-gated expeditions and loot scaled to player progress
  • Installable as a native-feel app on mobile with full offline play
