how do you play endless mode?
Viewing post in Die in the Dungeon CLASSIC comments
when you get floor 25 for the first time, boss frog kills you instantly. you got no option (if there is no easter egg or smt) .
so you need to play the game again. when you get floor 25 for the second time and beat the boss, game asks you if you want to finish the current run or enter the endless mode.
