Fill Fell Box (aka RGB Box)

This level shows some promise and it's OK when it works.

Spoiler: Issues

The problems are that the free draggable is not always easy to move around and having it fall down is particularly sticky. Since there is no backstop for the ball, I've had it shoot out off the game space. There is a lot of wasted game space within the back side of the box, but the art is easy on the eyes. My biggest complaint is that a player must figure out that the slider has to be in the open position (away from the win block) in order for the free-draggable to be able to fall all the way down - and that this needs to be done prior to falling the free-draggable. Since there is no hint to this beforehand and no sign of the problem afterwards, this, in my opinion, is a failure.

Thanks for the effort!
