Shrinking Pains is a free to play Visual Novel about anorexia.
This game is very short and features simplified art with anime-like sprites, all of which is presented in black and white palette, with lots of white portraying the emptiness felt by the main character. You can pick what to eat or reply, in case choice options will be presented, which will lead you to a consequential ending.
