The Veggie Friends: Curly Carrot Eddie Eggplant Pete the Pepper Sass the Squash Reception Kwirk received largely positive reviews. Reviewers praised the game's challenging difficulty. According to Mean Machines, which rated the game a score of 85%, Kwirk is one of the "simple, but very addictive" puzzle games, as stated by Julian Rignall. Because of the number of different screens, it doesn't "become boring quickly". Rignall stated the game gets "incredibly hard" and "really taxes" the player's brain. Matt Regan criticized that once the player has solved each puzzle, there is "no interest left". The German magazine Video Games reviewed Kwirk in its very first issue and awarded it a "Video Games Classic" due to a score of 85%. The magazine's editor Stephan Englhart praised the game's variety of modes and puzzles. He stated that Kwirk captivates with a "well-elaborated and harmonious overall concept" ("wohl durchdachtes und stimmiges Gesamtkonzept"). Console XS gave review score of 81% and described the gameplay as "pleasing and occasionally confounding" and opined that Kiwrk is one of the best puzzle games. Ports and sequels A port for the Famicom Disk System was released on November 16, 1990, and a port for the PC Engine on February 22, 1991. These versions were only released in Japan, and retain the potato protagonist of the Japanese Game Boy version. A spin-off called Spud's Adventure, known as Totsugeki! Valetions in Japan, was released for the Game Boy in 1991. It was published by Atlus in the U.S. instead of Acclaim. Unlike the first game, Atlus did not change the protagonist into a tomato, but left him as his original character of a potato. Unlike Puzzle Boy, it is an action/adventure game. A second sequel Amazing Tater (known in Japan as Puzzle Boy II) also for the Game Boy was released later in 1991 in Japan, and in 1992 in the US. Like Spud's Adventure, the protagonist remains a potato called "Spud". It retains much of the Mae play of the first game. In October 2018, the original game's North American publishing rights were acquired by Canadian production company Liquid Media Group along with other titles originally released by Acclaim.
