Pretty gruesome control setup.
Overall, the default controls aren't bad except for the option key.
But changing the others to something i prefer makes the option key an even bigger pain in the neck. Gotta be able to change the task manager to a different key.
Second biggest problem is the vertical mouse movement setup. I'm one of those people who cannot play a game decently if the mouse doesn't work like the stick on an airplane. Forward means lean forward, and back means lean back.
There's no control option to reverse the behavior as in many games, so i'm always looking at the sky when i mean to be looking at the ground.
