import Entropy from 'entropy.js';

const game = Entropy();

// register some comps, ents and sys
game.registerComponent({ ... });
game.registerEntity({
  type: 'Ball',
  ...
});

game.registerSystem({
  type: 'Movement',
  ...
});

// add some ents and systems
game.addEntity('Ball', ...);
game.addEntity('Ball', ...);

game.addSystem('Render');
game.addSystem('Movement');

// start the game
game.start(); // from this point the game loop is running, systems are updating

// stop the game, back to life
game.stop(); // game loop is stopped, no more updates
