Raylib is highly inspired by BGI lib and XNA framework. It is written in plain C and by default compiles to single static library.
Depends on GLFW3 (for desktop only) and OpenAL, both libs can also be easily compiled statically.
All raylib examples (60+) are ported to Go and there are a few more, for raygui (immediate mode GUI API) and for easings. Physics engine is on TODO list.
Android support is implemented with native_app_glue and NativeActivity, without any Java code. Go bindinds also support RPi, but I tried only with cross compile, not on a real device.
