Die, learn, and climb again!

A free-form dungeon-crawling game for immortals, where you can challenge as many times as you want.

◆You are an "immortal" challenger.
You climb the Demon Lord's Tower, filled with traps and monsters, dying and reviving over and over, starting from the very beginning each time.

But it's okay!
The more you die, the more experience you accumulate, gradually becoming stronger and harder to kill.
You can take the straightforward approach, try unorthodox strategies, or even brute-force your way through with cheats right from the start.

◆At the top of the tower--
The Demon Lord siblings watch your challenge through a crystal ball, providing live commentary.

"Why does it turn out like that!?"
"That's efficient."
"Don't die for efficiency!!"

You grow stronger through repeated deaths—can you actually reach the top floor?

*Only the "immortal" setting is fixed. Everything else can be freely customized.
