It serves no business, will never show up in a product meeting, and stands no chance of some manager asking for webhook integration. Even so, it forces you to deal with real problems. Screen, input, timing, sprites, sound, window, operating system. A toy like that teaches more about interactive software than a pile of CRUD apps dressed up as corporate demos.</p>
