Yesterday while playing legend of Grimrock, I fell through one of the many trap doors that litter the dungeon. Seeing how I've been very careful to avoid falling through trap doors up to that point, I expected this would lead to my prompt death, only to simply end up alive at the bottom (though the fall damage combined with some monsters took care of that).
Before dying, however, I saw that there was some exploration to do down there, perhaps even items? Generally, intentionally falling and hurting myself makes little sense, but perhaps there is much to be gained by jumping through trap doors?
If anyone has insight into this matter, I would appreciate it.
