Yume Noroi (ユメノロイ)

Overview
Yume Noroi or Yumenoroi (ユメノロイ, 夢呪) lit. Dream Curse is a Yume Nikki fangame made by Nueko. It stars Tsumetogi, possibly an older dreamer who seems to be a hikikomori.

Gameplay
Yume Noroi plays like most Yume Nikki fangames, but the main objective in Yume Noroi is collecting effects. You enter the "dream world" through the computer, and save at the papers next to the computer. Tsumetogi wakes up from the menu, and crawls out of her bed when "waking up". When an effect is collected, a glowing circle appears in the nexus, and you can place the respective effect (each effect is assigned a color) on the circle with Z, and interact with it again if you want the effect back.

Plot
Tsumetogi has many places of herself in her "dreams", she is possibly ashamed of something she has done, or herself. It seems as if she had problems in school and got very jealous over a crush. Using the nail effect on hearts causes a nail to be driven through them, that stays there, possibly meaning she was rejected or heartbroken by this person.

Warning: Spoilers for the ending of Yume Noroi (Highlight at your own risk) In the School World, Tsumetogi is shown smiling over the dead body of what appears to be her crush/someone she loved, for there have also been parts where both were shown smiling while holding hands with each other, and a giant hand separating the pair in the room with another Tsumetogi sitting all alone. After collecting all the effects and placing them on their respective circles in the nexus, going outside to Tsumetogi's balcony shows stairs that were not there before, and she then jumps off, similar to the ending of Yume Nikki.
