Mario vs. Donkey Kong: Mini-Land Mayhem! is a 2010 puzzle-platform game developed by Nintendo Software Technology for the Nintendo DS. The game was released in North America on November 14 2010 and is the fourth entry in the Mario vs. Donkey Kong series. Mini-Land Mayhem! received positive reviews from critics who praised its gameplay and level editor. A sequel titled Mario and Donkey Kong: Minis on the Move was released in 2013 for the Nintendo 3DS. Mario vs. Donkey Kong: Mini-Land Mayhem! is a platform game with a 2D level design. Similar to the old Lemmings games the puzzle-based gameplay in Mini-Land Mayhem is built upon that of the 2 earlier Mario vs. Donkey Kong titles where players do not control Mario but instead are tasked with guiding wind-up miniatures to level exits in this case mechanical Mini-Mario toys. The game requires players to "build and rebuild levels on the fly" to allow the small miniature Marios to get from point A to point B. As the mini-Marios cannot be directly controlled the player instead uses a stylus to manipulate their movements. Each level has one to three minis that must be moved and it is necessary to rescue all the minis to clear a level and each exit closes several seconds after a mini enters. If a mini falls onto spikes traps pitfalls run into enemies falls from a height of ten blocks or more or the timer runs out the player gets a game over and can either restart or exit the level. Once a single mini has reached the door a timer comes on and everyone else must be through the door within about six seconds otherwise the door will lock up leaving out any other mini toys behind and it's Game Over. Similar to Mario vs. Donkey Kong: Minis March Again! it is not possible to stop the miniatures or change their direction once they are activated.
