Take a look at this video to see the game in action.

Specifically jump to 1:10 through 1:18. You will see the character grabbing onto various ropes to get across. The player has to press the right sequence at the right time (when you here those noises) in order to make it to the other side. If they were to press the wrong way or not press the right one in time they would see a death scene displayed.
If you look here you can scroll down to the entry called "Burning Ropes" to see the sequence the player has to press. Guide for Dragon's Lair - Room/Scene Sequence (trueachievements.com)
The style of the game is not so much the animation graphics but the idea that video sequences are played. Death sequences for the wrong responses or the next sequence if the player does the right thing. Here is an example of someone who did a stop motion animation with clay that is a bit fast for a game but gives an example of what a sequence might look like:
If we were using this sequence where the yellow person loses their head that could be the death scene if the player decides to click the action button vs. if they had clicked to the side to hide which would then show a video sequence that advances the narrative where the yellow character hides. Sorry I am probably not providing the best explanation of what I am looking for.
