* SurpriseDifficulty: Adventure Mode looks like reliable and fun Crash fare, but anyone who has played the last four Crash games will notice how rotten this one can get. Might also count as a SequelDifficultySpike in relation to the Crash series as a whole. The cooperative mode, while no pushover, is easier since evens the odds with 2-on-2 games.
** The first game was pretty unrelenting as well, but the last three games before ''Bash'' (''2'', ''3'', and ''CTR'') were generally softer.
* ThatOneBoss: Like ''CTR'', the bosses are a LOT tougher in this game. Even Papu Papu puts up a fight, like in ''CTR''.
* ThatOneLevel: While Ballistix as a whole is infuriating, N. Ballism takes the cake. There are two gimmicks: Magnet powerups that repel the ball and N. Gin apearing and firing balls in a counterclockwise direction. Considering how the computer players [[TheComputerIsACheatingBastard can easily get the magnets]], the level becomes the hardest Ballistix level, even more than the next one. Which one's Crystal challenge is harder is up to you to decide.
