It's not bad, but without any goal it's not really a game. How about adding score, time limit, upgrades, achievements, stuff to make finding it more difficult, or anything else that would make it a game?
I've played better stencyl games, but in relation to what people post here - it's not bad. One thing though - If you want to kill the actor when you collide with the ball - that's fine, but make the ball's collision space in the size of the ball. Regardless of that matter - 3/5. It's not bad, but not worth 4 points.
Thanks for the comment, my first ever game :)
