Going to create my game in C++ and cross compile it to Linux, Windows, macOS and also a web version using emscripten.

Libs and tools I will be using:

• IDE: emacs
• Compilers: mostly clang and emscripten. Will be using a tool I wrote called bldr to easily build the project with toolchains setup in docker images.
• Graphics: SDL2
• Physics: Box2d
• Maths: glm

Base code will be here https://github.com/wiltaylor/ld-engine/ (will open it up in the next few days before the competition).
