We initially did our Ludum Dare game in C++ and SFML. But we saw that C++ & SDL could be compiled to WebAssembly with Emscripten, so my teammate @elvaka did the whole porting SFML -> SDL, and made it compile to WebAssembly, and now the game can be easily played from itch.io, instead of downloading the binary!
