Steam■ Game Overview
Monsters unleash outrageous attacks in randomly generated stages.
Face a bizarre and unpredictable dungeon in real-time in this roguelike action RPG!
The adventure begins now!

------------------------------
■ Story The leader of the “Party of Destiny,” known only as “J,” suddenly vanished one day.
He was a legendary figure known worldwide—famous for breaking the seals on petrified heroes, harboring planet-scale high energy in his belly, and even holding a Guinness World Record for dandelion blowing.
His disappearance sent shockwaves through the government, the people, the dogs, the cats—even the birds. Everyone was searching for “J.”
But “J” was in a place no one could ever find: a dungeon that existed in another dimension—his one lingering regret in life.
There, in solitude, “J” continued his lonely challenge to conquer it.

------------------------------
■ Stages
"Level 1 Stage" Begin at Level 1, Floor 1. No items allowed!
A true test of skill in a classic roguelike challenge. Will you make it to the top of the 100th floor…?
"Custom Stage" Custom stages unlock based on your play record, allowing you to bring items!
Choose your gear and strategy freely—take on the challenge in your own unique way! (…But if possible, we'd really love for you to try clearing the “Level 1 Stage” first~)

------------------------------
Planned for Future Updates
■ New Stage: "Battle Stage" A mode where you defeat waves of enemies to proceed to the next round. The enemies… feel different from the usual ones…?
■ New Items:
Stay tuned!
(To be developed depending on future sales)
