Wait until the bow is drawn (when the aim stops shrinking), and click anywhere on the stage to shoot an arrow ... or something else. Click the green flag to remove all objects from the wall.
In this remix, I made the following changes: + I added 32 extra costumes :) + I added another list in order to keep track of the costumes of the objects to render. + I added an ordering function, to make sure that the objects are rendered back to front (highest to lowest x position). + I split the "stamp active arrows" function into two parts - one for the objects behind the current "arrow", and one for the objects in front. In the original project, the arrows are simply rendered in the order they are shot, but since they are so thin, I figured that people wouldn't notice. But when I added the massive costumes in this project, it became very apparent, which is why I went through the trouble of ordering them ;)
