Unity mobile game development
Two years building a survival game with over 20 connected systems.
I was the sole Unity developer for this 2D survival game. I designed and built its connected gameplay systems, integrated the team’s art, audio and game design, and prepared production versions for Android and iOS.
My role and the team’s contribution
I was responsible for Unity programming. The team was responsible for art, audio, game design and balance.
My responsibility
I designed the code structure and built the gameplay, interface behavior, saves, progress while the player is away, language support and analytics. I also prepared the Android and iOS versions and maintained the Unity code as the game developed.
Team contribution
The team created the art, audio, game design and balance. I integrated their work in Unity and made it function together throughout the game.
20+ interconnected gameplay and technical systems
Resources feed production, production supports research, and research unlocks new options. The game saves each result so the player can continue in the next session.
The game tracks the player’s condition, items and resources as they take actions, move between activities and return to a saved game.
Players use resources in crafting recipes and production facilities. Each system updates the resources available to the others.
Research and quests unlock new options as the player advances through the game.
Players leave the base for expeditions and minigames, then bring their rewards and changed condition back to the main game.
The game also needs reliable saves, multiple languages, usage analytics and working Android and iOS versions.
How one activity leads to the next
Project code and content
These counts come from the project’s source files. They describe the amount of code and configured content, and do not measure player numbers or commercial results.
A unified JSON container, field-level persistence, autosave and pause/background saves protect long-lived state. Offline elapsed time is granted once and advances crafting, research, greenhouse growth, archive decryption, physiology and timed effects.
ScriptableObject-driven items, recipes, research steps, quests and status effects feed an event-based progression model. Inventory changes, research completion and other gameplay events can satisfy conditions and unlock the next state.
Physiology turns player parameters into ongoing survival-state changes. Expeditions add hex-grid risk, damage, injuries, rewards and quest validation before results return to inventory, economy and persisted state.
Firebase Analytics instrumentation, Android/iOS configuration, rewarded and interstitial ads, consent handling, in-app purchases, localization and adaptive audio all sit beside the gameplay architecture.
A public 25-minute review shows the Antarctic base, expeditions, research, production, survival-state management and embedded minigames working together.

This case documents engineering scope and publicly visible gameplay. It does not claim current store availability, revenue, retention results or work performed by the art, audio, game-design and balance team.
How I can help your project
Build a game or add features
Create a 2D or 3D Unity game for PC, Android, iOS or VR/XR devices. Start with a playable prototype, a small complete game or new features for an existing project.
Review and fix an existing project
Find out why a Unity game or app is failing, what can be reused and what needs fixing before you invest in more development.
Update an older game for testing
Repair an older Unity game or app, update its features and keep it working. If you plan a new release, I can also add usage tracking and prepare it for user testing.
Starting or taking over a Unity game?
I can build gameplay systems, review and improve code from a previous developer, or update an older game so you can test it with players.
