Adding even more scenes
To add more scenes, like we did before, we are going to click on the scene named "1" and press D on the keyboard to duplicate it.
Remember to delete the player in the new scene, and rename the scene to "2".
Be sure to move the enemy obstacle in a different location in the scene so that the game has variety.
You can add as many scenes as you want. Remember that adding more scenes means more variety in the game, so feel free to let your imagination guide you in the amount of scenes you want.
Properties of scenes
You have probably noticed that the scenes loop continuously, giving our game the endless appeal and trying to see how far you can get.
Additionally, the scenes are also in a randomized pattern, so you can ensure that you get a different variation of frames every time you play your game.
Making the environment more dangerous
Another way we can add more challenge to the game is by prohibiting the player to touch either the ceiling or the floor.
This is very simple to do. All you have to change is the collision group in the "Ground" asset, so that it is now part of the "Enemy" collision group.
Next lesson, we are going to refine the enemies' hit boxes so that the player only dies when it actually touches the enemy sprites.
