My 2D Platformer Code With Different Libraries

[Kapendev]

I spend some time trying to get the platformer code from Parin to 
work with other libraries.
It currently works with arsd.simpledisplay, raylib-d, and WASM-4.
I might add a pixelperfectengine example too, but got stuck at 
some noob stuff (a minimal hello-world example would be nice to 
have).

Here is the repository:
