Great now theres a whole army of little plumbers.
The game worlds are made up by the different floors of the building. The floors contain 9 levels and 1 boss level. This game isn't a platformer but instead, a lemming's like action puzzler. Each level as you escorting the army mini-Mario's (there's a different number of the toys you have to escort in each level) into a door way. You do this using your stylus, which is a neat way to do command the toys, and its also very responsive. You use the stylus to move the Mario's left, right, stop (if you don't tap them they will just keep going in the direction you told them to go), and make them jump. Sometimes it's hard to make them all stop when there traveling close. If one stops then the other will hit the one that has stop which cause these stopped one to start again, and the others too turn around in the other direction, and then everything can get jumbled up. You can also use it in certain areas to interact with the environment such as making a pink block walkway for the toys or, making a platform rise so you can get the toy's to a higher walkway. Each floor has a theme, which incorporates new environmental challenges. So it usually never gets boring.
After Completing each level you are scored on your time, number of coins obtained, how many Mario's went into the door one after another, and if you got the letter card for the level (more on the card later). The rankings are stars, the best is a gold followed by silver, then bronze, and the worst you can get is no star. Well the worst is not completing the level but don't worry the game isn't much of a challenge, each level takes about ½ a minute to a minute and a ½ to complete. The Puzzles aren't real mind benders. Luckily there are about 80 levels.
Now every level you're able to collect one card with a letter on it. Collecting every card in the level will spell out MINIMARIO and unlock a mini-game. The mini-games are all the same, just tap the objective number of shy-guys as they appear out of pipes (kind of like whack-a-mole), but don't hit bomb-ombs, and do it within the time limit. This is very simple and usually you do it before another very simple task. Boss fights.
The boss fights are shooting levels. You're usually shooting semi-live ammunition at DK who usually throws stuff at the cannon or hides, tries to do something to miss being hit by mini-Mario's. Yep that's right the ammo our mini-Mario's you saved in the earlier levels leading up to the fight. These levels are very simple and easy too, you basically just hit DK 6 times which will not deplete your ammo very much cause most of the time you'll have around 20 minis.
The game starts out with a CGI opening, and then converts to a somewhat 2.5D gameplay. The toy's and enemies are all in 3D but the backgrounds are in the basic 2D, colorful themes that you would expect from a Mario game. The Top screen is pretty much blank just showing, how many toys have made it into the door, and how many points you've scored. Though the exception to this is bosses where Donkey Kong is on the top screen and you're shooting your toys up at him.
The sound isn't too memorable, there is voice acting in the opening scene but that's just a advertiser telling about Mario's theme park. There are good sound effects like when the toys break or when they fall in water. Other then the sound effects, they've just remixed some of the old Mario songs.
The games story will only last about a hour to a hour and ½. You can always go back and try to improve your score, there are also basement levels that are unlock once you beat the main story. The coolest thing to do after the game is to make your own levels in the level editor, you can not only make levels but you can all play other peoples levels using WIFI, which makes the game have an unlimited amount of levels (if you have wifi).
Overall it's a pretty easy going, short game only lasting about and hour 1/2 for more experienced gamers, without the exception of level editor. If you're looking for something that's not much of a challenge or something for the little kids, then this maybe perfect for you. If you hate games that don't give a challenge then you'll probably won't like this. But I have to say this is a pretty fun game for a rainy day, or if you had a stressful day.
