Lift Movement

OK this is my first time even attempting to make a game(and I know SOME C++ and Java but not very much :/) so I'm gonna need a lot of help and might ask a lot of questions in my progress, so please don't get too mad at me. So what I'm trying to make is a quiz game, but not with a screen full of four huge boxes(one with the question and the others with the answers), them being a tad smaller so that the player can see the lift(like an elevator without doors) going up as they progress through each stage(there will be five). Any tips on how I could make the lift move like this? Should I make each stage a different scene or is it doable in one scene, if I make it 2D and put all the stages in one single background with the camera moving along? Plus, as of now I am absolutely clueless about how I could make the kick of the game work: when the player gets a question wrong, the lift will drop back to level 1, so that the player has to start over from level 1, but with a different(or if lucky, same) question within the stage. Can I do this with a waypoint, or would it be a better idea to make them separate scenes? Thanks a lot for reading, guys!
