* 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.
** The crystal challenges for it and the next one (Sky Balls) are very close in difficulty, though. In N. Ballism's crystal challenge, N. Gin will ''only attack your goal.'' This is somewhat alleviated by him shooting the balls in the same location every time and having bigger gaps between each shot, but still. Sky Balls could possibly be even worse. There are red balls that randomly show up this time, and they will kill you in one hit. Of course, [[RulesAreForHumans the AI can kick these all day]] without any issue. If they go through your goal, they don't count off; however, what really makes this a pain is that sometimes the regular balls will, completely randomly, turn red when a computer kicks one, and in many cases you will have no time to react. Have fun!
