I've always preferred Wario Land games over Mario platformers. While Mario has used conventionally safe mechanics, Wario games usually have all sorts of weird and experimental things going on for it. I've always fancied how they seemingly go out of their way to outright troll the player and punish heavily for missteps, almost as if there is someone carefully designing parts of the levels to take up as much of the player's time as possible. With the fourth iteration of the series that aspect has somewhat toned down and more weight is put on time trials. Every level has a switch somewhere in them that opens the end portal and starts the clock you need to race to finish while collecting whatever it is left to collect in the level.

Wario's movement remains pretty much the same from the previous games. You still have the charge and jump and the controls are really solid and satisfying. It seems that the developers dropped the powerups almost completely in favour of a larger healthbar. There are still some enemies that give the character status effects that often are required to complete puzzled for progression, but Wario himself has only one standard form to play around with.

Bosses are also more traditional platformer bosses with specific ways of beating them. Bosses and enemies overall aren't very hard by themselves, but most of the game's difficulty comes from navigating the levels, clearing the puzzles and completing the time trials. On normal, these all are pretty generous and a casual platformer player shouldn't have too much trouble.

The game's look and feel is pretty par for the course at this point. The graphics are well polished with well defined backgrounds and foregrounds, animations are all cute (as cute as Wario can be of course) and the music slaps. Each level even has a hidden cd you can collect to get the level's theme in your collection. While the "worlds" themselves usually have some overarching theme, each level takes you into a different place with it's own gimmick and look, so no single location is going to grow stale (outside of those hotel and domino levels of course).

While collecting treasures is in the core of the game, I'm kinda left missing the exploration and finding all sorts of hidden paths and unique artefacts from previous games. It seems that progression was made more straight-forward, so you'll probably spend a little less time with this one. There is some replayability with multiple endings and harder modes, which makes some minor chances, mostly just decreases the time you have to clear everything.

It's more Wario, a little less trolling and a stellar GBA game.
