If it's the latter, you tend to get more time. Hunting the undead is risky business. The tension in the game would have been markedly decreased had you simply been on a non-lethal stroll. You may feel differently though. The game is played entirely with the mouse.
Right click is for the inventory, left click for everything else.
To look around you simply move the mouse around - there is no need to click and drag, and your cursor always stays centre screen which seems to give you greater control over your viewing area. You have full 360 degree viewing, but there is no transition from scene to scene. Most of the scenes are totally static, but the cut scenes, and there are lots of them, are excellent. The voice acting is generally good. There are however no subtitles.
