This video will show you some of the things you can do to design your game and make it your own.

Click on any of the sprites and click on the costumes tab.

The starter project came with several costumes for each of the sprites.

You can choose one that you like.

You can edit costumes in the paint editor.

Click on the sprite, and you will see a box around the whole sprite.

To edit the sprite click the ungroup tool.

This lets you change individual pieces of the sprite.

Click on a single piece.

You may be able to ungroup further.

This example ungroups one further to tinker with the arms.

Click on the pieces you want to change.

Click the dot in the center to move the piece, to rotate it, click the dot.

Click on the squares around the piece to change its size.

Click the reshape tool.

Dots will appear around the outside of the piece.

Drag the dots to change its shape.

Click the pencil to draw on the sprite.

Choose colors from the color selector.

The line, box and circle tools will help you draw those shapes.

You can type using the text tool.

To change the color of part of a sprite, select the color you want, the paint bucket, then the area that will change.

Be fearless and don't worry about making mistakes.

Computer scientists like you make mistakes all the time.

They are great opportunities to learn.

If you make a mistake, use the undo button and try again.

Deleting a costume by pressing the x in the top right corner, or start from scratch by deleting all the costumes and painting your own using the paint new costume button.

Use these tools and techniques to edit the characters, objects and backgrounds in your project.

Have fun exploring.
