Broken Bottles

 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, who explores her subconscious by means of a chemistry set. The artistic motif is, as would be deduced, glass and bottles in various forms: maps, doorways, effects, etc. (chemical tubes could also be seen as "bottles"). It follow's Nikki's premise somewhat faithfully:

The game seems to be fairly well-received.
