SYNECHRON'S PROFILE

Hello,

I was looking for a game I've found some years ago,
but at the time it was too scary for me to try.
I was curious to try it again. But I can't remember the name...

I think it was quite an unknown game. It was very aggressive game
with skeletons dancing and some sort of different kind of skeletons
in a sort of hellish looking setting...
You couldn't save unless you were able to talk to a specific skeleton
and I also remember they were a screamer near the begginning...
I don't recall as well that there was a particular story or gameplay...
More like exploration and random aggressive scary stuff...

If anyone has any idea, what this game could be?
thank you
