Broken Bottles is a Yume Nikki fangame created by a user called "Doodle" (tumblr and pixiv accounts). You play as a young girl named Dokutsuki. Her name roughly translates to 'Poisoned'.
"It holds the same main idea as Yume Nikki, you explore a girl's subconscious by falling into an induced sleep and you find what may lie in her mind. It might have a meaning, it might not, you decide. This game is intended to have a dark atmosphere, but it may be happy at times. You start out in a corridor of doors, pick the one you want to start in while you explore. The effects change what the character looks like and sometimes their abilities. If you equip the same effect twice, you will return to your normal self. Just wander around and enjoy."
