Rooftop Rampage

Rooftop Rampage is the ninth level in Crash Twinsanity and the final stage of Madame Amberley's Academy of Evil.

Description
The level serves as a tutorial for using Nina's character and shows Cortex the skills that Nina has learned during her time in the Academy of Evil. The level takes place mostly on the night-time rooftops of the academy, though Nina will occasionally enter small portions of the school. She must use the school's gargoyles to traverse as she can grapple onto them with her bionic hand. The roofs are festered with rats and ants who will try and stop Nina's progress as well. Inside the school, the academy's Zombots will also attack the player. Some of the school's chimneys are unstable and will collapse under Nina's weight. Additionally, she must spin through bells when she comes upon them to pass.

Eventually, Nina will be followed by the airship, since Crash anchored it to a school bus which wasn't heavy enough to weigh it down.. This bus ends up becoming a hazard for Nina, as it dangles from the airship and destroys the bridge she is walking on from behind. After getting out of the bus's way, Nina will meet up with Cortex, who sends her back to the airship.

The player takes over as Cortex and fights Madame Amberley in her office, the boss fight of the level.

Gems
Blue gem: The blue gem is near impossible to miss. It's in the middle of the path, and you swing into it while grabbing a grappling ring to progress.

Clear gem: The clear gem is also impossible to miss. It's in the middle the third wall jumping section, and you swing into it while climbing.

Green gem: The green gem is in clear view, on a tower you reach after going inside for a bit. Jump on the bouncy crate underneath it to grab it.

Purple gem: The purple gem is on a set of collapsing chimneys. You can collect it as you jump through.

Red gem: The red gem is at the end of the bus chase. You collect it as you swing through on the grappling ring.

Yellow gem: Immediately after the red gem, there is a ! crate in the corner of the platform. Trigger it to make bouncy crates appear on the next platform. Bounce on the bouncy crates to reach the gem.

Boss fight - Madame Amberley
Madame Amberley is suspended over a pit. Cortex is standing on the valves of a giant organ. The boss starts with Amberley shooting lightning at valves, causing them to pop open and spray hot air upwards, damaging Cortex if it touches him. When a valve is open, Cortex can't get around it. He must shoot the valves closed again to stop them from trapping him.

After doing this for a little bit, Amberley draws back and lauches bells towards Cortex. Cortex must shoot the bells back at her. Failing to shoot every bell causes Amberley to taunt you and go back to electrifying valves. If every bell hits her, she spins around, exposing her back.

Shooting the mechanism on her back damages her by 1 hit point, also severing one of the ropes that are suspending her. She has 3 hit points. After removing all of her hit points, therefore severing all of the ropes, she falls down into the mist with a high pitched screaming sound and is defeated.

Trivia

 * Players can, if the jumps are timed right, hop around the bells.
 * It is possible to spawn in Rooftop Rampage as Nina and Cortex together. However, if players move without spinning, the game will crash due to incomplete code.
 * This is the only level in the game where Crash isn't played as (without hacking or using glitches, that is).
 * This level is the one of the only two times in the game where you can play as Nina, the other being the final boss against the Evil Twins.
 * This level is the only time in the entire series that Madame Amberley appears in person.
