Use the mouse to do just about anything! What to do when changing body parts/clothes: When clicking on the red-and-grey buttons in a parts section (eg "Ears") click on the grey parts to switch the actual body part, and click on the red to select the part without changing. The multicolored bar is the color picker (used to select the color of the selected part) and the long white to black bar is the brightness picker (changes the brightness). Click on the small white cube to make the body part white/grey/black (depending on brightness).
This was just a fun little project made over a few weeks. Feel free to suggest any accessories/parts/clothes/whatever to be added to a new version of this game! Maybe I might make a Scratch forum to let people show off their creations and make suggestions. Credits: Sonic the Hedgehog is made by SEGA Scratch for... Scratch.
