The fitting background music, the nice animations when the vegetation pops up and the absolutely beautiful wisps make for a really great atmosphere. A few tiny issues i noticed are that the player sometimes gets stuck in the middle of the wisps (maybe you could make the player ignore collisions with wisps?) and generally could use a bit more movement speed. The happines meter also appeared to be completely full even while i was still missing large parts of the map. Other than that, a really cute game with amazing atmosphere!
