From the publisher's website:
Danse Macabre is a relatively rules-light dark fantasy game with an emphasis on mood and horror. The game works around player characters of relatively insignificant power in a world full of cosmic horrors, monstrosities and dark things. Helplessness is not only potentially a part of the game, it is generally expected.
This means that Danse Macabre stands at quite a remove from traditional fantasy or epic fantasy games. The expectation is that players will have to tread carefully and slowly through a given game session. Problems will usually have to be solved through clever reasoning, not brute strength, and it's quite likely that player characters will have to simply make a run for it when dark creatures turn up.
In short Danse Macabre is a game of careful survival, not glory.
It is recommended that Danse Macabre is suited for a mature gaming group. Some elements of the game have an adult, sometimes philosophical, sometimes horrific theme.
