City Builder – Resource Management Game

Project Overview

City Builder is a resource management and simulation game focused on long-term progression, economy balance, and scalable gameplay systems. The game was developed to run on both WebGL and Android.

The primary goal of this project was to design reusable and extendable systems for buildings, resources, and progression rather than one-off gameplay mechanics.

My Role & Responsibilities

• Designed core city-building and resource economy systems
• Implemented building placement and upgrade mechanics
• Created scalable progression and unlock systems
• Balanced resource generation and consumption loops
• Optimized simulation performance for WebGL and mobile
• Ensured cross-platform compatibility and stable frame rates

Engineering & System Design

Resource Economy Architecture

The game uses a centralized resource manager that controls generation, storage, and consumption of all resources.

• Single source of truth for resource data
• Event-driven updates to UI and gameplay systems
• Easy addition of new resource types

Building & Progression Systems

Buildings were designed as modular entities with upgrade tiers, allowing scalable expansion without refactoring core systems.

• ScriptableObject-driven building data
• Upgradeable production and capacity values
• Progression-based unlock flow

Cross-Platform Optimization

Special attention was given to performance constraints of WebGL and low-end mobile devices.

• Reduced per-frame calculations
• Cached frequently accessed data
• Optimized UI redraws and simulation ticks

Challenges & Solutions

Challenge: Preventing economy imbalance

Early versions allowed players to snowball resources too quickly, breaking progression pacing.

Solution: Introduced production caps, upgrade costs, and exponential scaling to maintain long-term balance.

Challenge: Performance on WebGL

Solution: Reduced simulation frequency and avoided unnecessary allocations to maintain smooth performance.
