The NES game Nuts & Milk is a puzzle platformer released in Japan and a year later in the US and Europe. The game was originally released for Nintendo, then moved to other consoles.
The plot of Nuts & Milk unfolds in a fantasy world. A blob named Milk must save his lover named Yogurt from Nuts. In each level, Yogurt is imprisoned and Milk must get to her by collecting all the fruit scattered around the location. In doing so, Milk must avoid colliding with the Nuts roaming the map. Once the player gets to the bride the game goes to the next level. The difficulty is that each location has a different landscape: walls, stairs, bounce springs, bridges, etc. In order not to run into a nut you need to think quickly how best to get to the top floor and in doing so collect all the fruit.
Nuts.
On the whole Nuts & Milk isn't a bad and sticky game, it's fairly well known because it came with a cartridge with the console in most cases. But, that's probably the reason why it hasn't become so popular among gamers.
