Critics gave the game moderately positive or below average reviews. Aaron Roberts of Nintendojo said "Basically, Atomic Betty is a better-than-average game for kids, and one that will keep them on their mental toes, to boot". Nintendo World Report's Ben Kosmina said "The game is fun" but added "it's not going to last you a long period of time", after completing the game within 2 hours, he also stated it has "absolutely no replay value". GameZone's Michael Lafferty stated "this is obviously a game targeting younger players and in that regard it succeeds in providing an entertaining, though short-lived, experience".
