Not sure this is the right place to post a question on construct. If not, please move this to the right place.

Trying to move platform between Edge Animate and Construct 2. Though I am an expert in Edge Animate, please pardon my utter ignorance of construct 2. 

Done 2 tutorials here but I still have a lot of questions.  I am trying to use Construct for a drag n drop educational game and there are hardly any tutorial about it. 

I posted a sample done in Edge Animate to give you an idea of what I want to do.

I have several questions to set up the game. I want a screen intro - then an info screen - then the game.
how do you slide a screen off the stage like you would do with animate    animate({'top': - 400},1000);
would that be a good way to move between screens?
should screens be on different layers?
when on the game screen, how to replicate the drag n drop system like in jquery-ui draggable/droppable 
is it possible to add classes so I can track the correct answers?
