Instructions in-game Don't mind the very wonky Scratch Cat. fine. if you scrolled down here just to find the instructions, fine. here you go: Move Scratch Cat by dragging him or by using the arrow keys. If he goes too high (even if you are dragging him) he will fall. And break. And lose a heart. Move the ladder by dragging it and change the height by clicking it. The red pulsey thing is the itch. It'll glow green if you hover over it. To scratch the itch on Scratch, press the space bar. It won't scratch the itch if you aren't on it for long enough.
