Phantom Grid

A native iOS arcade game built in Swift and SpriteKit. 15 BFS-verified levels, enemy AI, haptic feedback, leaderboard system, and 6 control schemes. Live on the App Store — free, no ads, no in-app purchases, no data collection.

PHANTOM GRID

iOS arcade · Swift + SpriteKit · 2026

▸

15 hand-designed levels — each one BFS-verified so every gold orb is guaranteed reachable from spawn. No unwinnable states ship.

▸

Fixed-timestep loop — identical gameplay speed on any device, from 60Hz phones to 120Hz ProMotion displays.

▸

Independent enemy AI — each guard runs its own chase/patrol state machine with unique timing offsets so they never mirror each other.

▸

6 control schemes — D-Pad, Drag Anywhere, Joystick, Follow Finger, and dig button overlay. Every player finds their style.

▸

Teleport exit sequence — collect all orbs and your character power-surges out of the level with a Super Saiyan flash.

Under the Hood

Architecture decisions that matter

Every choice in this project maps to a real engineering tradeoff — and a real interview answer.

⏱

Fixed Timestep Loop

Game logic runs at exactly 60 ticks/second regardless of display Hz. Discovered when the web prototype ran 2× faster on a 120Hz MacBook than a 60Hz phone — then fixed before any code was ported to Swift.

accumulator += delta
while acc >= 16.67ms {
tick()
}

🔍

BFS Level Verification

All 15 levels run through a Python Breadth-First Search before being built into the game. Every gold tile guaranteed reachable from spawn — no unwinnable states ship to players.

verified: 15/15 levels
gold tiles checked: 312
unreachable: 0

🤖

Enemy State Machine

Each enemy has independent walkSpeed, thinkInterval, and goal state. Staggered start timers prevent mirroring — enemies feel like individuals rather than clones running the same script.

enum Goal {
case chase, patrol
}
thinkInterval: 4 + (i % 4)

🎨

Theme Abstraction

All colors, shapes, and collectible types live in a Theme struct. Swapping worlds at runtime is one property change — the renderer never hard-codes a single color value.

ControlScheme.dpad
ControlScheme.joystick
ControlScheme.dragAnywhere
// player picks their style

📱

Coordinate Bridge

HTML canvas is top-left origin (Y down). SpriteKit is bottom-left origin (Y up). One gridToScreen() function handles all conversion — the rest of the game never thinks in pixels.

y = frame.height
- row * tileSize
- tileSize / 2

⚡

Scene Graph Rendering

SpriteKit creates tile nodes once at level load. Only changed tiles (dug holes) update. Canvas drew all 308 tiles every frame. This reduces per-frame work from O(n) to O(1) for static tiles.

// node created once
// only holes update

The Story Behind the Build

Questions this project answers

The decisions behind Phantom Grid are interview answers. Here are three of them in full.

"Tell me about a technical challenge you diagnosed and solved."

The game ran twice as fast on my MacBook as on a phone — a frame-rate dependency bug. Game logic was tied to requestAnimationFrame, which fires at the display refresh rate: 120 times/second on a MacBook, 60 on a phone. I implemented a fixed-timestep accumulator — the same pattern used in AAA game engines — that decouples logic from render rate. Game logic now always runs at exactly 60 ticks/second regardless of hardware. I caught this in the web prototype before touching Swift, which meant the architecture was correct before porting began.

"Why did you choose SpriteKit over Unity or other game engines?"

SpriteKit was right for the initial iOS build — native, zero overhead, direct Metal access. After shipping to the App Store I made the deliberate decision to port to Unity for Android/Google Play distribution, rebuilding the entire codebase in C#. Choosing the right tool for each stage of a product's lifecycle is part of good engineering judgment — and something I apply from 18 years of QA systems design.

"How do you use AI in your development workflow?"

Three levels. Architectural pressure-testing — I use Claude to challenge design decisions before writing code. If I can't explain a choice to an AI that will push back on it, it's not a good enough decision. Autonomous implementation — Claude Code agent in Xcode 26.3 handles boilerplate, build errors, and refactoring while I focus on system design. Contextual learning — I ask it to explain Swift concepts in context of my actual codebase rather than textbook examples. The core discipline: every architectural decision is mine. AI is a force multiplier, not a replacement for judgment.
