There are several different dangers that can be found which will instantly kill you (forcing you to restart the current level). Two such things are bowling balls (which can fall on you) and arrows (which can shoot you). They are often sitting there just waiting to go off, or sometimes they are blocked by some other object that you will need to move or pick up, allowing them to go off. One important fact is that all such devices are stable when you are next to them - even if you are at the "business" end of it. For example, you can pick up a chest that is underneath a bowling ball by walking underneath it, but at that point, if you move down, the ball will fall, flattening you.ｿ
