Except in maggot lair when you couldn't kill a baby maggot on normal difficulty and he was halting your progressiong through the maze. So you have to leave the game and join another one. You say aiming your hammers wasn't hard, but you weren't allowed to aim them. You just used them and hoped they hit something. You could position your body to try to get them to go where you wanted them to, but they still did what they wanted.
