A little background on this game: I was in my computer programming class (of which I was just relearning everything I already knew anyways) and the class was assigned a project. The project was to create a game in BASIC that would teach elementary school kids some kind of skill (spelling, speed math, history facts, etc). The game I made was called FireWall. In the game, there were viruses trying to attack a computer. Each virus had a multiplication expression and the computer had a number on it. You had to click the correct virus to keep playing the game. To my surprise, many of my highschool friends really liked the game. So for my first homebrew game, I decided to create a remake of FireWall (not a port! the DS one is still very different).
