I made this by experimenting with the "effect" block. It works a lot. With this project, you can learn how the brightness effect and the color effect affect a sprite, and also potential levels needed for the requirements. *instructions* Use the mouse to adjust the color of the square (can be any color that scratch allows). You can also press the "R" Key to reset everything and the space key to change the background. You can also drag the square to where ever you wish.
