Live Coding Kotlin - Native Snake
summary
Live-codes a playable Snake written in Kotlin/Native that uses ncurses for terminal UI, Gradle for builds and Kotlin/Native C interop via LLVM, with tiny unit tests for movement and turning. Builds a 1.6MB standalone binary, implements apples, growth (growthSpeed = 3), and halfDelay 200ms input; memory uses reference counting plus memScoped/defer for C allocations. The game runs, grows when eating apples, and dies on wall or self collision.
