I never played much of the Mario vs Donkey Kong series, and saw this on the Nintendo eShop on my 3DS and thought, "eh, looks like a port to the original arcarde game, only in black and white, which is lame." Like many others, I was so wrong! I read more into it and figured I'd shell out four bucks for the download. Best four bucks I have ever spent! You start out with the original four levels arcade, the last one included which was left out in the NES version. Other than the improved appearances of the characters and backgrounds of the original game, only in black and white (or if you're using the Super GameBoy peripheral for the SNES, color with the arcade cabinet and slightly improved sounds). At the end of the fourth level, you defeat Donkey Kong and save your girlfriend, Pauline. You can choose to turn off your GameBoy or exit the game on your 3DS... or you can let it play out as Donkey Kong rises back up, smashing the ground, making you, Mario (aka Jumpman), and Pauline fall. Poor Pauline falls into the arms of that donkey of an ape and chases off with your girlfriend (Mario's secret girlfriend... Don't tell Peach!)! You have to chase after him in 9 more worlds, resulting in 97 more puzzle-platforming.
