Very neat game!

I had trouble figuring out what to do with the animals though, until I checked the comments here.
Maybe the deer could give you more of a hint. I tried clicking on the notes appearing over its head which immediately ended the singing-action and after I knew what to do it was still kind of tricky choosing the right spots at first xD

I had a small error in the beginning (using Chrome) where I went into the screen with the mushroom lover the second time, double clicked somewhere in the scene and suddenly there were two of me - and then the game froze in confusion :D
