compile a native executable or a transpiled JS browser version with
emscripten.
This front end is pretty feature rich, allowing testing etc. A much more
minimal could be made. If you want a learning example of front end, look at
another, simpler one, e.g. the terminal.
To compile with emscripten run:
emcc ./main_sdl.c -s USE_SDL=2 -O3 --shell-file HTMLshell.html -o game.html

Demo support is very basic and isn't mean for users, it is there for

SDL's multiplatform input system is used, with demos enables smallinput
