Broken Bottles

Broken Bottles is a Yume Nikki fangame where you explore a girl's subconscious by falling into an induced sleep and you find what troubles lie in her mind.

You start out in Dokutsuki's room. Once you have fallen asleep, you can choose from many doors in a corridor to start exploring her subconscious. The effects change what the character looks like and sometimes her abilities. Just wander around and enjoy.
