Have a go hero - Extending the game

That's it. This is our little game. Of course, there is much room to improve and extend it. For example, you can add some barricades Benjamin has to jump over. Then, you would have to check whether the player item collides with such a barricade item when moving forward, and if so, refuse movement. You have learned all the necessary techniques you need for that task, so try to implement some additional features to deepen your knowledge.
