Wario's movements are controlled quite well with the D-pad operating his running and jumping (which can be inversed with the X, Y, A buttons for left-handed players), while the opposing hand is free to manipulate the touch screen. Costumes are changed by drawing shapes around Wario and the game's most definite issue is whether or not the game will recognize a player's drawings. While overall annoying, this problem becomes triply frustrating when costumes need to be changed in a split second for situations such as boss battles. Even spelling words to answer riddles was a chore as it seriously took me almost five minutes to get the game to recognize the letter "T."

Touch screen controls are further pushed by the ultra repetitive and lame mini-game diversions used to disarm traps found in treasure chests. The menial tasks throw objectives such as "trace this object," solve sliding picture puzzles or connect the dots. None of the mini-games are particularly fun, especially after doing them dozens of times, and merely seem like yet another excuse to use the touch screen.

While the touch screen mechanics can come across as extremely frustrating or tedious, there is still a bit of fun to be had in Master of Disguise. The levels feature clever design that requires players to use every power at their disposal to reach the end. Furthermore, players can replay levels after receiving new powers to search every nook and cranny of an environment for treasure.

Even though the treasure mini-games will tie players up for a bit, the average level will occupy someone anywhere from half an hour to an hour. Regular save points will save players from having to re-do an hour's worth of work as they scour the expansive levels for as much treasure as they can. With 10 levels in the game, players will be looking at between 10-15 hours of game play, a suitable total for a portable adventure.

While Wario: Master of Disguise doesn't live up to many other platforming titles, it still provides a decent romp through the Wario universe. Aside from poor usage of the touch screen, the title still retains Wario's platforming charm and wacky use of powers. With a little patience and the will to try something a little different, players should be able to get enough enjoyment out of Master of Disguise for at least one play through.

Wario: Master of Disguise is rated E 10+ (Everyone 10 and older) by the ESRB for Crude Humor, Mild Cartoon Violence.
