You can use these basic sprites if you want or need to focus your time on the more challenging aspects of making a game.
If you tend to finish your assignments early, I recommend finding assets that are more to your desired theme.

Instructions

Step 1:

Open your game from the prior assignment. Use "Save As..." to save it with a new name (e.g. "Platform Playhouse 3").

This will serve as a backup and allow you to return to a working copy of your game if something goes wrong.

Step 2:

Add an enemy to your game. Also, add two invisible marker objects for left and right movement. Make your enemy move back and forth between the marker objects.

Step 3:

Add events so that the player and enemy interact with each other. The enemy will kill the player when they collide except when the player is jumping onto the enemy.
