Yume 2kki (ゆめ2っき)

Yume 2kki (ゆめ2っき Yume Nikki, literally Dream Diary) is the original fangame that started it all. It is a collaboration project from 2chan.

The game is about a girl named Urotsuki. She seems to be a hikikomori like Madotsuki.

Just like the original games, there is no plot and the only goal is to explore and collect all of the effects.

The game is currently uploaded at the yume2kki_4 uploader at loda.jp, along with many other fangames. Older versions are found in theyume2kki loda.jp uploader. It's usually split in four parts.
