Although certain parts of the game were cute and wonderful, much of the game was lacking. The fact that you need to be directly touching an object to interact with it feels unnatural. Also, if you click on an object from too far away or hold down the mouse button over a too-far-away object, the character stops moving which also seems very unnatural.
The music is set on a loop and, given the situation, doesn't really fit with the tone of the game. The game takes place in a forest, so a classical music piece highlighting the xylophone would probably work best.
The clay characters are very cute and well done. The overall scenery is also cute and well done, but the trail animation when the character is walking doesn't really match the scenery. The trail animation that you used is commonly used for puddles or other shallow water sources. The bunny in the game is walking in, what I assume is, grass. In this case, the best thing to do would probably be no trail animation.
Gameplay seems almost too easy and unoriginal. Stars aren't really "hidden", so they're easy to find. Many search-and-rescue games already exist. Granted, most of them don't have the character choose only a few individuals to bring back to the base/basket, but that's because there's a lack of motive to only bring back a handful of individuals.
