    I've built a store implementation that allows name-spaced actions and helps with the separation of concerns. The new Composition API in Vue3 also allows completely new, convenient ways of using it.

  <p>
    I will tell you how I created a simple top-down shooter in JavaScript without using any additional libraries. But this article is not replicating the full game but instead tries to show which steps to take to start writing a game from scratch.
