Hi all,
stumbled over a little nethack-clone named "Lost Labyrinth DX".
https://www.labydx.com/index
Table has only two scripts - one to get unlimited character perks at creating a new char, the other one lets you boost your character stats unlimited (available attribute points do not decrease when spent).
Since everything is one-hit after your stats are high enough, no other things like godmode necessary 
have fun,
Marc
