The game's ports received varying levels of praise. The four reviewers of "Electronic Gaming Monthly" reviewed the PlayStation and Saturn versions, commenting that the audio and cinemas in both versions were cleaned up compared to the 3DO original. They especially praised the game's humor and solid platforming action. Tommy Glide likewise stated in "GamePro" that the PlayStation version had "cleaner graphics and smoother gameplay" than the 3DO version. He also remarked the Saturn version has "the same graphics, sound, and control that earned acclaim in the PlayStation version", and held it favorably above "Bug!", another platform game for the Sega Saturn. "IGN" stated that the game was still as fun on the PlayStation than it was on the 3DO, despite noting that very few changes had been made. "Next Generation"s review of the Saturn port remarked that "Gex" was nowhere near as fresh as it was when it debuted on the 3DO, but still witty and fun. In a negative review of the game, Rob Allsetter commented in "Sega Saturn Magazine" that although the visuals and game flow were acceptable, they were both negated by the game's "utter predictability." "Maximum" gave the PlayStation version a mixed review, saying that the player character has a remarkable variety of abilities, but that the level design is often dull and frustrating. Wildgoose praised the PC port of the game, stating that it was still enjoyable despite calling it a "slightly aged console platformer".
