WASD or Arrow keys to move the blue player and hold Q to sprint. Press Z to show/hide the variables on top. Customize this however you want with these variables that i made. The toggle ??? thing activates a shadow of scratch cat that follows you around. In night mode, it gets less transparent and it gets faster.
Click the green flag and see the sprite depth sort themselves. For the amount of cats/trees to change, click the green flag again to see the effect change
