Make a monster. Use the mouse to click on the name of the body part you want to add. Right and left arrows change the look of the body part. Up and down arrows change the size. Click and drag the body part to the spot you want. If you want to change a body part, click on the name again. If you want to remove a body part, click and drag it to the garbage barrel at the bottom right of the screen. When you are done making your monster, click on the yellow "to finish" button. Finally, choose a background using the right and left arrows. Click on the yellow "to choose" button to choose the background and complete your artwork.
Minor fixes - you should be able to choose features and switch between different styles. When you are done and choosing a background, don't try to move your character. You'll take it apart. If you want to move your monster, you'll have to move it one piece at a time. Thank you to Emily, Simon and Spencer for testing out this game! Thank you to deck26 for advice via the forum!
