Question:
I need help with generating a levelmap for Kaboom.js, and update the level every time.
Repl link:
Bean Platformer

import kaboom from "kaboom";

kaboom({
  background: [51, 204, 255]
});

loadSprite("bean", "sprites/bean.png");

...

const bean = add([
  sprite("bean"),
  pos(80, 40),
  area(),
  body()
]);

onKeyPress("up", () => {
  if(bean.grounded()) {
    bean.jump();
  }
});

onKeyDown("right", () => {
  bean.move(200, 0);
});

onKeyDown("left", () => {
  bean.move(-200, 0);
});
