Markmos Engine

A cross-platform game engine built from scratch — Metal backend for iOS/macOS, Vulkan backend for Android.

Written in C++23 with no exceptions, no RTTI, and no engine hiding the details from you.

Features

• Renderer abstraction — Metal (iOS/macOS) and Vulkan (Android) behind a unified RHI
• Sokol-style architecture — markmos_main() as the single cross-platform entry point
• Audio via miniaudio
• Memory via rpmalloc
• Job system for multithreaded tasks
• Sprite batching with draw call sorting
• C++23 — no exceptions, no RTTI, no unnecessary abstractions

Build
