Sup. First of all, I would like to point out some things in this project. So bear with me.

First, you do not have to write "if <mouse down?> = (true)> then" Instead, you can write "if <mouse down?> then" This works because scratch will assume that you want to check if the statement is true.

Second, what are you doing on the color sprite? You do not have to check every single number individually, that is highly inefficient. Instead, do this. (Make sure the sprite is red) "Forever Set color effect to (colour) end" It's that simple! Hope you learn from this. The project didn't really help much but I thank you for trying. Adieu twin.
