Simple and effective with a well executed artistic vision. If I were to add a touch of anything, it would be creature sounds to add a sense of playful interaction and make the forest dwellers stand out more (otherwise the jingles get repetitive). Animations for hugs and hand-holding would also be exceptional if time allowed it (something I would've added in my own game too).
The only minor immersion-breaking bug is when the creatures walk into me after I help them, then disappear. Otherwise this experience is smooth with no faults.
