IIRC, Wario Land 3 has no health or lives. Enemies can only modify your state. Wario Land 4 walked it back a bit by adding hearts, but most of the game is still a movement puzzle, where you have to get flattened to walk under narrow passages, lit on fire to turn to ash and fall through gratings, stung by bees to swell up and fly like a balloon, et very cetera. And then every level ends with a timed dash back to the entrance.
