๐ใScary Halloween๏ผ๏ผใ๐
โโWelcome to the eternal Halloween!! ๐ป
A world where an unnervingly massive full moon floats in a purple sky. Countless bats flit through the air, pumpkins move on their own, and laughter echoes from empty alleys. The streets are adorned with orange and black decorations, and there is no distinction between day and night. This is the otherworldly realm where Halloween never endsโใScary Halloweenใ. โจ๏ธ
In this world, every day is Halloween! Even when morning comes, the sun never rises, and the clock hands remain fixed at midnight. Open a door seeking treats, and you might find yourself in an unknown mansion; walk down a path, and you'll end up back at the cemetery you just passed. The residents laugh cheerfully and repeat their merry parades, but look closely and you'll see everyone is a bit... off. A headless knight searches for his dropped head, and ghosts crawling out of graves offer directions. It should be terrifying, yet it's somehow silly, making it impossible not to laugh. It is a strange and delightful world. โ(ยดใผ๏ฝ)โ
However, there is one major problem with this world.
Once you wander in, you can never return to your original world?!
The only way to escape is to find the hidden exit somewhere in the world before the night of Halloween ends. But in a world where night lasts forever, what exactly does it mean for the "night to end"?
Even when encountering horrific events, some scream, some burst out laughing, some start taking commemorative photos, and some aren't even listening in the first place. The escape drama is always pure chaos. Yet, it's not all fun and games. Shadows creep up behind you in a sudden moment, and voices call your name when no one is there.
Will Guest be able to escape safely from Scary Halloween? Or will you yourself become a merry resident of this world, joining the eternal parade...!
Now, don't forget the password.
Trick or Treat๏ผ๐๐ฆ๐ธ
โโEven if you give me treats, I'll still play a prank on youโช
