At one point, theres a glinting pixel you need to pick up.
If you fail to before you are forced out of the screen (which you can never return to) you will find out about 1-3 play hours later that it was important...and then you die.
In KQ5's defense, by that point in the game, you were so used to clicking anything that did ANYTHING that you had to be pretty blind to miss the big, shiny flash that the locket item gave off in the Roc's nest.
Of course, the fact that you got so hair sensitive to even the most inconsequential details simply beacuse you never knew what ANTHING was for....
Ok. Those old Sierra games are only cool 'cuz they are nostalgic.
Except "The Castle of Dr. Brain". That game was awesome.
The Roc's nest was actually the second time you had to pick up a glinting pixel in a severely time-limited screen to which you can never return. In the Ali Baba cave, you have to pick up the genie's lamp, which is obvious, so you might think that was all you needed there. But you also needed the nearby gold pixel, dummy!
This is definitely the worst by far of the King's Quests, yet it was the first one I ever played, so therefore I love it.
The cat that appeared the second time you walked by the inn, an early location, before you had the boot, an item obtained via a complex maze you probably wouldn't be ready for until later.
