File:Crash Bandicoot Prototype, Part 18 Cortex Power-0

Description
The biggest difference here is the camera angle, which makes it more difficult. The entrance is also different with a big door first and then Pinstripe's "SAFETY FIRST" door from Generator Room instead of Cortex's "N" symbol. There's also a glitch in the final room that some times ends the level before you jump on the platform. Other than that, there's nothing major that I can think of, but I don't think there were that many masks in the original.
