Watch out! Dr. N. Brio isn't far and an evil crate bridge tries to stop your quest for the gem! Be fast and escape the Castle Machinery! - Level description
Castle Machinery (きかいかは すすむ lit. Mechanization is Proceeding in Japanese) is the twenty-seventh level (including boss fights) and is the tenth level of the third island in Crash Bandicoot and the Crash Bandicoot N. Sane Trilogy remaster of the first game. It is right before the boss fight against Doctor Nitrus Brio. If the player has obtained the green gem, a secret platform appears right next to where the level begins, taking Crash up to a secret area that has many extra lives (27 in the original game and 29 in the N. Sane Trilogy), preparing him for the forthcoming challenges. There is then another platform there that takes Crash to the end of the level. Oddly, this is the only level in the game with a secret gem route with crates only in the main route. In fact, taking the full gem route will cause the player to miss all the crates in this level. It is the last factory type of level in the game. The Tawnabonus round in the previous level, Jaws of Darkness, saves at this level.
Translation of Aku Aku Hints in the Japanese Version
As you've advanced here properly, I'll teach you the way to defeat Brio. The medicines thrown by Brio are his evil souls. Jump to defeat them.
Out of all the levels in the game, this one has the most lives that are not in any crates.
Castle Machinery doesn't exist in the prototype. It was one of the last levels created for the game (along with the long Tawna bonus round and cutscenes). This is odd considering that most of the power plant levels were among the first to be created. The level was most likely created to replace Stormy Ascent.
On the PAL version of the game, Crash does not say "Whoa!" when he gets killed.
