Urotsuki's Games Console, which vaguely resembles a SNES, can be used to play various minigames when not dreaming, and is found in Urotsuki's Room, next to the TV.
Games
Various Minigames are playable from the console's menu, by scrolling left and right through the cartridge list, and pressing the Action key (z) to select the game.
Red Blue Yellow
The Red Blue Yellow game has no given name, and is similar to an Arcade Defense-shooter.
You play a diamond-headed character, who changes color based on what color projectile you are given. The aim of this minigame is to shoot down the ever advancing Circle-headed characters with their corresponding colored projectile, who are constantly getting faster with each advance.
Projectiles go through multiple enemies, and it is possible to take out multiple enemies of the same color with one projectile. Projectiles are given to you in a random style comparable to Tetris, and at times you may get the same colored projectile multiple times in a row.
The game is over when an enemy reaches the first line of squares that you are defending, and will display a Game over screen, showing your score.
↑V↑ (Wavy Up)
↑V↑ is a puzzle game with multiple stages, you begin outside some sort of office building, and after seeing a ghostly girl on an upper floor, you begin to explore the building. A full walkthrough of the game can be found on this page.
As of versions 0.99, this game has not yet been finished, and will end after the chase scene through the mansion. Beating this game unlocks Wallpaper #56.
PUZZLE GAME (Kura Puzzle)
The Kura Puzzle Minigame is a slider-puzzle game, featuring over 40 Kura Puzzles for the player to rearrange and solve. These are collectable like wallpapers, and are unlocked through meeting various conditions in the dream world.
Plated Snow Country
The Snow Gunikki Minigame is an exploration-based minigame, not dissimilar from the play style of Yume 2kki itself. In this game you play a blue 'Snow Gunikki', and search the icy map for ice-related effect items, to free another gunikki, trapped in a formation of ice. Upon collecting all the items, you can enter the cave that you started infront of, and proceed to the final area. There are slots shaped like the collectable items in the walls, and placing each of them into the correct slots and proceeding ahead will yield the Good ending. Going on ahead without placing the items into each slot will give out the Bad ending.
FUJI
FUJI is a ridiculously futile minigame, keeping very much with the stlye of Yume nikki's original NASU game. The title screen is translated poorly, drawing on NASU's dodgy 'engrish' menu as influence. In the minigame itself, you play a very slow moving Mt. Fuji, and the aim of the game is to try and shoot falling birds with fireballs, launched from the peak of the mountain with the Action key (z). You begin with three lives, and for each bird you miss you lose one. The game is over when you have lost all of your lives, where it will promptly show you your kills, time, score, and your all time High-score.
This game is unlocked after you've given the girl in Christmas World her present.
Gimmick Runner
Gimmick runner is a Lode-runner style minigame, where the aim of the game is to run to the finish of each level, avoiding obstacles, flipping switches to open doors, and collecting Glowing yellow diamonds for extra points.
As you move throughout each level you can save your progress by running past green checkpoint poles, and upon death, you will respawn at the last pole you activated. At the end of each level, you are evaluated on the difficulty of the level, your overall clear time, and the amount of yellow diamonds you collected.
To quit the game, you have to climb down the ladder underneath the Gimmick Runner Sign in the overworld, upon exiting urotsuki will awaken from her bed. (possibly because the game is unfinished) As of versions 0.99, the game is still under development, with one playable level out of a total of 15.
