Yoga? Now for TWO big surprises!
The first: There are alternate endings to the game.
The second: I'm American.

I come from German blood, but born American.
Ohne Mitleid is a nickname given to me years ago because in high pressure situations, I can act without emotion, even if the outcome may be damaging to myself.
I hope you were lying down when you read that.
A couple more things... I noticed you listed Gothmog as only carrying a compass. That's another tip: don't leave hands empty. An empty hand can always carry a club, stone or boulder (or anything else) that you can grab and throw at an enemy.
This is something I tried, but I wasn't fast enough with the mouse. When you swing your weapon, you have to wait until the character is ready to swing again. But if you are quick enough, strike with your weapon, quickly grab their weapon out of their hand and drop it back in again and viola! They are ready to strike again immediately.
