It is mouse and keyboard. There are only 2 times in the game you have run from monsters. I just hid behind a rock until the one went around the corner! Otherwise, it is exploring, developing the story and puzzle solving. You move from a blizzard to underground caverns to a deep sea voyage in a submarine to a dilapidated mansion to shifting sands under the desert... very rich and varied environments.
In my PC corner for the winter, my little heater by my side, to game, read and knit.
