Mechanics Portfolio
Technical deep-dives into specific mobile game systems. Explore implementation details, architecture decisions, and performance analysis.
Implementing Box2D on iOS requires careful memory management. We allocate physics worlds in background threads to prevent frame drops during intense combat sequences. Our Unity integration uses a custom collision layer system that reduces CPU overhead by 40%.
- Fixed timestep implementation for deterministic behavior
- Object pooling for rigidbodies and colliders
- Raycast optimization for input detection
Modern mobile devices range from 4-inch SE models to 7-inch tablets. Our UI framework uses constraint-based layouts with dynamic scaling. All interactive elements maintain a minimum touch target of 44x44 points, ensuring accessibility across the full device spectrum.
- Safe area handling for notched devices
- Vector-based assets that scale to 4K
- Dark mode support with automatic detection
iOS terminates apps exceeding memory limits without warning. Our profiling toolkit identifies texture bloat and excessive draw calls. We implement texture atlasing and aggressive unloading of unused assets between game sessions, keeping peak memory usage under 150MB on older devices.
- Instruments profiling for iOS builds
- Android Profiler for leak detection
- Adaptive asset streaming based on RAM

Peperse.com Field Guide
These aren't abstract theories—this is the practical framework used to ship real titles that perform well across device generations and market conditions.
Decision Criteria
- 1. Device Age Range: We target a 5-year device window. If it won't run smoothly on a 2019 iPhone SE, redesign the mechanic.
- 2. Touch Accuracy: Buttons smaller than 44px violate iOS Human Interface Guidelines and frustrate players.
- 3. Battery Impact: Particle effects and polling loops drain batteries. We profile every frame for energy efficiency.
- 4. Session Length: Mobile games are played in bursts. Mechanics must deliver value in 30-second sessions.
Myth vs. Fact
Myth: "Graphics sell mobile games."
Fact: Gameplay retention drives revenue. We've seen 8-bit puzzle games outperform 3D shooters because the core loop respects the player's time.
Myth: "Freemium means pay-to-win."
Fact: Ethical monetization creates long-term value.
Myth: "One size fits all."
Fact: Tablet UI cannot be a scaled-up phone interface. It requires rethinking navigation and touch targets for a different hand position.
Key Terms Glossary
- ECS (Entity Component System):
- Data-oriented architecture that improves cache locality and enables massive entity counts.
- V-Sync:
- Vertical synchronization that caps frame rate to the display refresh rate to prevent tearing.
- Draw Call:
- Command sent to GPU to render geometry. High draw calls = poor performance on mobile.
Common Mistakes
- Hardcoding UI positions instead of using constraints.
- Using uncompressed audio files that bloat app size.
- Ignoring safe areas on modern iPhone models (notch cut-off).
- Allocating memory in the main render loop (causes stutter).
- Testing only on high-end devices (performance cliffs on older hardware).
How It Works
Our development workflow follows a systematic approach to ensure mechanics are tested, optimized, and scalable before full production.
01
Define Goal & Constraints
Identify the core experience and device limitations. Set FPS targets and memory budgets before writing a single line of code.
02
Choose Approach & Validate
Prototype the mechanic in isolation. Profile performance, check input responsiveness, and validate against accessibility standards.
03
Apply Method & Example
Integrate the mechanic into the main loop. Implement object pooling and optimize draw calls. Test across actual devices, not just emulators.
04
Review Results & Actions
Analyze metrics: retention, battery usage, crash rates. Iterate based on data, not assumptions. Ship the update or rollback and rethink.
Performance is a Feature
In the mobile market, a game that runs at 60fps on a 5-year-old phone earns more trust than one that stutters on the latest flagship. We believe optimization isn't an afterthought—it's thermal throttling, memory pressure, and real-world network conditions.
- Cross-platform architecture
- Memory-efficient asset loading
- Predictive input buffering
Why It Matters
Player reviews frequently mention performance before story or graphics. A single stutter during a critical moment can break immersion and lead to uninstalls.
Our internal metrics show that games maintaining 99.9% frame stability see 3x higher day-7 retention compared to those with frequent drops.
