It has some bugs (fe. enemies being disabled by push) and in my opinion it's extremely unbalanced, unless I am missing some stuff going on.
It seems like rushing to next floor is only viable, because of how character is weak - and I guess that's the idea of the game, but it's easy to get trapped between 3 monsters. Poison shouldn't be as a trap, because it's random. Health in this game is a very limited resource.
