As soon as you step through the gate, it closes behind you and the action begins. So check your equipment and make any changes beforehand. (See the notes in the main walkthrough for tips.)

Move into the area between the two gates.

As you step forward, the gate behind closes, while the one ahead opens. White circles on the floor show where spikes are about to pop up. Jump across the gap to the upper right.

More spikes prevent you from going farther at first. Watch the floor and when you see white circles, quickly move onto a safe spot before the spikes pop up. This happens several times, so stay alert.

When it looks like you're boxed in and the only 2 safe tiles are about to be filled with spikes, don't panic.

Just wait for the strips along the left and right to clear and move to either side.

Shortly afterward, the rest of the spikes will retract so you can jump down onto the ledge below.

Take a running jump across the gap to the right. Follow the walkway forward and around to the left...

...then right again to snag a MAX HEALTH UPGRADE before jumping across the next gap onto a wide, flat ledge.

This is where the Challenge: Survive the Final Battle without Using Weapons or Bombs occurs. Watch the floor and move off the white circles before more spikes emerge.

After a moment, random enemies begin to spawn as well. These may be skeletons, exploding mummies, etc., with varying element types. I mostly encountered flaming varieties, but there were some frozen ones as well. I believe the types vary with the weather outside. If you're attempting the challenge, don't use weapons or bombs. Just do your best to avoid both enemies and spikes.

This goes on for a few minutes, with spikes popping up in different areas. If possible try to run/roll away from the enemies...

...so they end up in the spikes or on the other side of them from you.

Rinse and repeat.

...

Again, when it looks like you're boxed in and the only safe tiles are about to be filled with spikes...

...it means you're almost done. Just wait for the areas on the left and right to clear and move to either side.

A moment later, the last remaining enemies should impale themselves on the spikes and you'll receive another MAX HEALTH UPGRADE for your efforts.
