Press the green flag to start. There are instructions on each background. I just noticed a mistake in the notes & placements! Oh no! I will change this the next moment I can (update: rerecorded and adjusted placement).
Sounds were recorded from my keyboard. (There are still a few problems I would like to figure out... Sometimes the birds go behind the bins (update: solved! I found the "go to front" command) and I am not sure why the gray bar will not go all the way to the end (update: solved! I had the center of the bar too far off to the right rather than on the bar itself). I am very open to suggestions. Oh no! a new problem... the birds in the 3,4,5 slots end up all the way at the end. I will try to fix this.)
