Instructional Animation Game

I am trying to develop an "instructional maintenance" game in which the user steps through the game and an animation and text are displayed on the screen during each iteration. The idea is that the user will be able to go back an forth through various steps of instructions (like removing a tire from a car) and the animation and text for that step will be shown. The animation will display various components being removed throughout the game. Any ideas of the best way to accomplish this?

Thanks Everyone
