Mickey's Adventures in Numberland
Mickey's Adventures in Numberland (referred as Mickey's Adventure in Numberland on its cover) is an educational Nintendo Entertainment System game starring the famous cartoon character Mickey Mouse. Gameplay. In this game, Mickey must collect all of the numbers from one to ten in order to prevent the evil Pete from completely robbing Numberland. The five levels are: Number City, Number Factory, Space Center, Number Museum, and Pete's Hideout. Basic math questions must be answered in order to progress to the next level. There are three difficulty levels; players can only "die" on  the hardest difficulty level. Also, the player is given balls of bubblegum to be used against enemies as a weapon. These elements create a "traditional video game" environment to an otherwise "purely educational" video game. The hardest mode of the video game also has a secondary function: to teach children about the basics of playing side-scrolling platform video games.
