Shadow Dancer: The Secret of Shinobi: Round 4: In The Darkness
6A majority of Round 4 takes place inside of a dark cave.
3-1 seems rather standard with being a cave level. Just march forward with Yamato and save more hostage while killing more hostiles.
3-2 has parts of the area shrouded in darkness. The hostage can still be seen, but not the enemies. You can try to use Yamato to sniff them out BEFORE you even get to see them, though.
3-3 has you face against the Wheel of Fire on top of a falling rock. It mostly can't hurt/kill you except for when it launches its fireballs at you.
In the very small moments when it stop spinning, but before it completely engulfs itself in flames, you have to hit the glowing yellow center of it to defeat it.

In the previous video. I've shown that you can go without shooting any ninjas in the Bonus Round and you can still get a 1-UP. Here, I show that if you miss a single 1 out of 50, you can still get a 2-UP, or you could just hit 48 and get a 1-UP like that.
Now onwards to the Final Round!
