Stencyl Training

I'm trying to learn how to you Stencyl. I started by trying to make a simple ping-pong like game, and I'm already bumping around errors and bugs I don't understand completely why they happen. Here's a small recording of what I managed to do.

I'm thinking of trying one of the crash courses they offer where they show how to make a Space Invaders style game. I hope I get to learn a bit more with it.
