Overview
Yume Nikki 3d is a 3-dimensional fangame starring Madotsuki herself. Unlike previous attempts to bring Yume Nikki to a 3D environment, it is not a replica of the game. It holds a bit of elements from the original game, along with some new elements/worlds.
Gameplay
Madotsuki moves at a nice speedy pace by use of WASD keys and can jump by pressing space and use items/keys with E.
You quickly flow through dreams by walking through portals.
The objective is to collect the three keys, which are hidden throughout the dreamworld, to unlock the exit.
Plot
There isn't any.
