Wario Land 2 moved the Wario series into the puzzle-platform genre by eliminating the element of death and adding temporary injuries, such as being squashed or lit on fire, and specialized powers.[6] Wario Land 3 continued this tradition, while Wario Land 4 was more of a mix of puzzle and traditional platform elements. The Game Boy update of Donkey Kong was also successful and saw a sequel on Game Boy Advance: Mario vs. Donkey Kong. Klonoa: Empire of Dreams, the first handheld title in its series, is also a puzzle-platform game.[7]
