A very melancholy, and surreal game about a social introverted girl who won't go outside(probably due to some sort of personality disorder) and has disturbing/psychedelic dreams. Draws heavy inspiration from games such as Earthbound and LSD dream emulator.
The developer Kikiyama created the game back in 2004-2007 and has not been heard of for years since (fans theorize he/she is dead and this game was their last cry for help).

1. A mobile dress-up game where you follow the story of a cute girl called Nikki and her friends and dress up in beautiful clothes
2. Try to survive without VIP while you anxiously hold together your last 347 diamonds before a new event starts
3. If you thought it had a shitty plot and was a harmless game YOU ARE WRONG
4. It turns pretty political and shit after your Cloud-Godess Lunar gets stabbed by a war-criminal
5. Prepare for suffering and sad backstories in the feature Dream Weaver
6. The fandom has progressed past the need of a (fairly good-looking but an asshole) war-criminal
7. The fandom will protect the precious characters
8. The main-character pretty much gets a harem but her girlfriend Kimi ist still her most beloved
9. Oh also a petty cat that isn't a cat called Momo will roast your styling skills
10. The devs do wierd stuff but try to figure it out without using tumblr to check event-spoilers and advice

A sexual ritual where one individual (the Strawberry) faces ass out on the bed with pink lipstick around the anus and has googly eyes on each butt cheek. During this sacred ritual you must play the song "Strawberry Kisses" and shake your ass accordingly. The other party will then partake in a light kissing of the asslips while the Strawberry honks on their crack pipe.

To excessively overthink an action or decision to the point of confusion in ones ability to make the choice.
I cannot decide what loafers to choose, I am really nikki-ing this decision.
I have done so much nikki-ing trying to decide what colour to paint my big toe.
