Hey, it's that Lemmings game with Mario characters...
Mario vs. Donkey Kong: Tipping Stars (Wii U) &
Mario vs. Donkey Kong: Tipping Stars (3DS)
It's another
Mario vs. Donkey Kong game by Nintendo Software Technology! There's not much new this time -- the game offered an online component in which you could earn stars in the game and "tip" them to the creators of other levels, and a few new minis -- Mini Luigi and a "Cursed" Mini Mario (with a monkey on his head). The big new innovation is that the same game was released on both the 3DS and Wii U -- buy one, and you get a free download code for the other version.
The gameplay is essentially the same as in most the other
Mario vs. Donkey Kong -- guide mini-Marios to the exit of the level, avoiding obstacles and collecting items. You don't directly control the minis, instead stopping them and manipulating the environment to get them to the end. A full level editor is included -- the "tipping" mechanic allows you to reward fellow gamers for their creations by gifting them the stars you've earned -- earning stars in this way helps unlock bonuses.
The game itself was developed using the "Nintendo Web Framework," which was supposed to make it easier for game developers to create new Wii U and 3DS titles using standardized, web-based technology. The game also featured Miiverse support and stamps (no longer accessible due to the shutdown of the Miiverse).
