Cosmic Trap

The Problem

Wanted to prove I could ship a polished product end-to-end, solo — from game design to both app stores. Chose a mechanic that requires non-trivial engineering: real-time area capture with arbitrary polygons.

The Solution

Built a 2D arcade game where you steer a ship to draw lines that fence off territory from drifting asteroids. The core mechanic uses Clipper2 polygon boolean operations and LibTessDotNet tessellation every frame — CAD-grade geometry under a mobile frame budget.

Technical Highlights

• Real-time Clipper2 polygon boolean ops (union/difference) + LibTessDotNet tessellation every frame
• 32-level hand-authored campaign with 4 asteroid types and dynamic win threshold
• Custom iOS ATT bridge in Objective-C++ with automated Xcode post-build hook
• Mediated ad monetization (IronSource/LevelPlay + AdMob + Unity Ads)
• Event-driven architecture, object pooling, thread-safe singletons, coroutine-driven game loop
• Solo: design, programming, SDK integration, store submission on both platforms
