* EarWorm: The theme music.
* GameBreaker: In Time Warp, you can exploit viruses in the otherwise very difficult ''Genius'' level of Primordial soup to gain easy wins [[labelnote:Note]] The way viruses work is by infected a cell when they touch it, causing them to decay much faster and explode, which creates more viruses. [[TruthInTelevision Y'know, kind like how real viruses work.]][[/labelnote]]. So either you could wage an epic battle against the incredible competent enemy cells, or you could infect one of your cells, send it into enemy territory, let it die and watch as the enemy slowly but surely die out as the virus spreads throughout their battalion in a hopeless war while you watch from a safe distance, you monster.
* SurpriseDifficulty: Some puzzles are a lot harder than you expect when you turn up the difficulty.
* ThatOneLevel: There's going to be at least one puzzle in each game you'll decide you hate. Most likely the one which targets your weakest area.
