Loading balloons from image now.  A white-on-transparent image defines the location of balloons in the level.  There isn't a way to trigger them, so for now they stay put, but in the future maybe they could have other images to define velocities and only be released when just off-screen.
Counting missed balloons, removing them from list.  Next recognize when level is over and move to new levels or start over.

Drawing grass with dog on it.  Next allow dog to move, and bone treats for dog.
Dog can move now, but needs to be tuned, key input is more generic but not completely finished in that regard.
