Crash Twinsanity (Walkthrough) - Part 28 35
Pitfalls are abundant in this level like all others.
There are more Nitros in this level than others, but are mainly found as walls that are easily avoidable.
Since this is a humiliskate level, TNT plays the same role as Nitro.
Going too fast and touching Evil Crash and Nina with hurt Crash and Cortex or cost them a life.
Ants will appear out of drills in this level, and hitting them or getting slashed by them will cost Crash and Cortex an Aku-Aku, or even a life.
- This is 1 of the 10 skippable levels in the game.
