DreaMarbleng
DreaMarbleng is a Yume Nikki fangame, based upon Irotsuki's dreams. As opposed to most fangames, instead of refusing to leave her room, the protagonist refuses to leave her house.
Every time Irotsuki sleeps, you earn 1 Credit as "money" of this game, which can redeem a game guide or a single-time speed boost from the desk in real world.
