About 750,000 copies were sold by 1995.
Computer Gaming World approved of
Flashbacks "superbly rotoscoped graphics", "fluid movement", and
sound card audio. Criticizing the awkward interface and use of
save points, the magazine concluded that it "is an excellent game that truly creates a sense of reality".
Electronic Gaming Monthly praised the SNES version for having improved graphics and music over the Genesis version. They remarked that
Flashback is slow-paced at times, but retains the player's interest through its compelling plot and involving puzzles.
MegaTech magazine conceded that although there were "five big levels", finishing the game did not take very long. Jim Trunzo reviewed
Flashback: The Quest for Identity in
White Wolf #38 (1993), giving it a final evaluation of "Very Good" and stated that "Even gamers not including toward arcade entertainment will quickly become engrossed by
Flashback. It's a tough but fair challenge. Players will grow fascinated as this sci-fi mystery unfolds screen by screen."
Electronic Gaming Monthly commented that the Sega CD version is "virtually identical" to the Genesis version, but that
Flashback is still an essential purchase for those who do not already own a different version.
GamePro, in contrast, argued that the reworked cutscenes "look so awesome that even gamers who've already completed this game on another platform will want to play it again just to see all the new CD footage". They also praised the addition of a CD-quality soundtrack and voices. A reviewer for
Next Generation acknowledged that the Sega CD version makes considerable improvements, but argued that they are all standard cartridge-to-Sega CD enhancements which have no impact on the gameplay. However, he lauded
Flashback itself for its graphics, animation and "fiendishly clever puzzles", and said that though the game superficially resembles
Another World and
Heart of the Alien, it is "in a class by itself that easily surpasses them".
Entertainment Weekly similarly said that
Flashback held up well, but that the Sega CD version's improvements seem less significant than its frequent load times. Reviewing the Jaguar version,
GamePro noted that it was merely a straight port with no enhancements to take advantage of the hardware, but that "the game is no less enjoyable" than when it was first released to game consoles over a year before.
Next Generation reviewed the Macintosh version, praising the animation, story sequences, plot, level design, and longevity. Its 3DO review stated that "this title is still the same great game that we've been looking at for a couple of years. And one last note, the 3DO controller, for once, doesn't interfere (much) with the game's demanding control scheme."
Flashback was listed in the
Guinness World Records as the best-selling
French game of all time. The Mega Drive version became a bestseller. In 1994,
Mega placed the game at number eight of top Mega Drive games of all time. In 1997,
Electronic Gaming Monthly listed the Genesis version as number 92 on its list of the "100 Best Games of All Time", calling it "a strong package that is fun to play even today.
Flashback makes us feel like we're
in that alien world, and with its lifelike animation and excellent moves, we can't help but love it." In February 2011,
Wirtualna Polska ranked it as the 17th best Amiga game and the Polish edition of
CHIP ranked it as the tenth best Amiga game. In 2004, readers of
Retro Gamer voted
Flashback as the 65th top retro game. In 1994,
PC Gamer UK named
Flashback the 17th best computer game of all time. The editors wrote, "
Flashback proves that, when it comes to producing original, stylish and challenging games, there are few more adept than the French."
IGN ranked the game 79th on their list of the "Top 100 SNES Games of All Time". In 2018,
Complex listed the game 43rd in their "The Best Super Nintendo Games of All Time." In 1995,
Total! placed the game 24th on their list of the "Top 100 SNES Games", lauding the rotoscoped graphics, which it said at the time were "the most realistic animation ever seen in a platformer". They also praised the combination of action and adventure-style puzzle challenges, summarizing: "The game itself is a [..] of an experience and the excellent plot also keeps the whole thing incredibly atmospheric." In the same year,
Flux ranked
Flashback tenth on its list of the "Top 100 Video Games". In 1996,
GamesMaster listed the Mega Drive version 59th in its list of the "Top 100 Games of All Time". ==Legacy==
