This is a great fan game, DEV. AMAZING!!!
Mumei will be proud of this game with relaxing BGM, deep meaning story and intereting mechanics of the game (especially the pull or push thing in this game to keep going to the next level). I already finished it :-D. Here is my 5 minutes+ gameplay. Enjoy~ "We've got all the time in the world" is my favorite sentence in this game. (Sorry for bad audio in the beginning of the game, though. Hehehe)
