Weird, I found ANOTHER glitch. Go to level 20, and place one of the Chimes right under the Ball Dropper. turn on the power button, and the ball dropper will destroy itself! This won't help with beating he level since yo destroy the power button and a Chime in the process.
How to get best ending: First go to town. Then go to the park. Then click on the the forest. Go left and drink all the water in the lake. You will see a crack. Keep clicking on the crack until you get the treasure.
