Update 0.87 really just involves my deciding to change the layout of the bricks in the room to provide the balls with proper room to reflect between the walls of bricks. (The spacing between the walls used to be just 16 pixels and now has been changed to 48 pixels) The number of bricks in each green wall has also been reduced by one layer and each green wall now has 9 less bricks than before to provide room for this extra spacing between the walls. That's it for this update. Have fun out there!
