Difficulty level

[Caterpillar]

I just started the Penumbra Overture and I have a question:
the difficulty level, in which way can change the game? Enigmas, enemies or something else?

[Sexbad]

All puzzles remain the same. Difficulty level changes the anger of the monsters. On hard they tend to cause more damage and run faster. They may see you more easily, but I have not taken note.

Mmmh ok I think I will set the hard difficulty

They may see you more easily, but I have not taken note.

Me neither.
Mostly it's just damage they make to you and speed they can run.

The enemies get tougher, on easy you can throw rocks on the dogs in order to kill them. On hard, the rocks have no effect.
