window should close

★☆☆☆by Ramon Santamaria (@raysan5)

There is no browser build of this example yet.

Is it the same as C?

Desktop:builds The Zig version builds, but it is not compared with C, because the C example does not give the same frame twice: requires interactive Y/N key input to exit; times out headless (both builds).
Browser:not checked yet The browser comparison does not cover this example yet.
