Idtipsa is a Spanish Yume Nikki fangame made by Chesilitia, starring Nex. It was created in RPG Maker 2003.
Idtipsa is a traditional Yume Nikki fangame. Nex's bed is used to access the dream world. The goal is to explore the dream world and collect effects. You save using the radio in Nex's room.
You play as Nex, a young person unable to leave their room.
Since Nex is a genderless person, all of the effects (with the exception of the Mirror effect) changes them into either a boy named Nox, or a girl named Nix. The menu type will also change from black to either light blue or pink depending on Nex's gender. The list below will refer to Nex accordingly.
Nix wears a blue cheerleader outfit and a yellow headband, allowing her to kill NPCs with a baton. Pressing Shift makes Nix show a pair of pink pom poms.
Nox wears a gray suit and a hat. Pressing Shift causes Nox to smoke a cigarette and become invisible to some NPCs.
Nix wears a pink dress and a mask over her eyes, increasing their speed more than the Dancer effect. Pressing Shift makes Nix jump.
Nox has a cloth tied around his face as well as shackles tied to his hands & feet. Pressing Shift makes him remove the cloth from his face, showing a bleeding hole underneath it.
Nix becomes a normal-size fairy, lowering her speed. This allows the player to see hidden objects. Pressing Shift causes the top part of her hair to open up, revealing a tiny girl inside.
Nox wears a blue one-piece outfit, increasing his speed. Pressing Shift makes him spin.
Nix wears a flower shaped skirt. Every time Nix is hit by a chaser, she loses a petal. Losing all petals forcibly wakes Nix up. Pressing Shift makes her look ashamed or disgusted depending the number of pedals.
Nox becomes a mushroom. Pressing Shift makes him release spores and return to the Nexus.
Nox/Nix becomes a boy or a girl randomly if there is currently no effect equipped. Pressing Shift changes Nox's/Nix's facial expression.
Nex becomes a mirror. Interacting with some NPCs while this effect is equipped will allow Nex to copy the NPC's appearance. Pressing Shift shows a face in the mirror and resets the effect.
