Going to copy/paste a reply I made to a different thread since I believe it highlights just how severely the current control scheme can get out of hand.

If you want to cross the chasm unharmed you need to unchain all four characters, select them one by one, jump across the chasm, move the characters out of the way to make room for the others (but without stepping on the explosive mines), select all the remaining characters and jump across, then continue to move through the passage without triggering the explosives on the other side as well. If you fail this at any point you'll trigger a mine which deals enough damage to take 1/2 of a character's health on top of leaving a puddle of fire on the ground.
