1998 · Platform · Game Boy
Wario Land II (1998) is Nintendo's Game Boy platformer in which Wario cannot die: enemy hits cost him coins or transform him, and some transformations open new paths.
Captain Syrup and the Black Sugar Gang steal Wario's treasure, and he sets off to get it back. There are no timers, health or lives. Hidden exits lead to different endings, and finding every treasure unlocks five alternate endings and a "Really Final Chapter".
Takehiko Hosokawa directed it at Nintendo R&D1, and it came out in March 1998. The colour version averaged 88% on GameRankings.
