Most games of this genre (merge) give players a daily case of energy to keep playing, this one doesn't. Add to that, not only do resource chests cost energy to empty, but it also costs energy to harvest, so you end up being able to play for about 5 minutes before having to either spend gems to refill energy or just turn off the game. I'm only giving 2 stars because the art is very cute and I love the dialogue between the animals.
