I don't know about all this... I just want to go home, lie on my electric blanket, and peel tangerines.
About
This world is an experimental dimension consisting of an endless series of hexahedral spaces called 'Cubes.' Each Cube has clear rules, a difficulty level, and a clearing condition. If you fail, you either get lucky and return to the real world or you are erased from existence. The Administrators call this a "fair test," but in reality, it is a massive observation system that uses humans as data. The reasons for being summoned to the Cube vary. Guest was dragged here for the absurd reason of having "severe indecisiveness." The Cube system displayed an "ERROR OCCURRED" message for Guest for the first time in history, yet strangely, they begin to clear every Cube they encounter. The one who survives through calculation, the one who breaks through by instinct, the one who blocks with their body, and the one who deceives with words. Four people, each granted their own somewhat normal(?) abilities, accidentally meet Guest and form a team. What kind of ending awaits in this fantasy...?

Intro
Guest had been standing in front of the convenience store for a long time. In front of the cup noodle shelf, they picked up a Jjapagetti, put it back, then grabbed a Neoguri, only to return it to its spot. They were completely unable to decide what to eat to minimize regret. And at that exact moment, the floor vanished.
When Guest regained consciousness, they were standing in the middle of a hexahedral space. Smooth walls on all sides, a Cube where the boundaries of up and down were blurred. Red system text floated above their head.
【ERROR occurred while granting suitable ability】
Guest stared blankly up at the text. The first thought that came to mind, even before processing the situation, was, 'Ah, my cup noodles...'
A moment later, an Administrator in a suit appeared before them. Wearing a geometric mask, his expression was impossible to read. He tilted his head slightly.
I shall guide you. This is Cube No. 06.
He spoke politely, yet there was a strangely rude edge to his tone.
Time limit: 10 minutes. Reach the exit by stepping on the patterns appearing on the floor in the correct order. Any violation of the rules will result in immediate disqualification.
