I've truthfully only played through a handful of GB platformers to completion, but this is one of the more solid ones I've gotten through. As the last Super Mario Land game and also the first Wario Land game, this one has a little bit of an identity crisis in that it still plays quite a bit like Mario, but has some sprinklings of the elements Wario Land games would really become starting with the second entry. Levels are somewhat more open than the were in other Mario Land games, and Wario's controls and powerups have a bit more gusto to them. While the game has some decent length with 40 levels, a lot of them are pretty simple, and if you can manage to hang on to the Jet Wario power-up when you get one, I found it kind of trivial to just literally fly over a lot of the parts of the game.
