Nice graphics! You should add persistence on the game, this way, the user could not start from the beginning! Rated 4 stars in almost everything, good job!
Recommendations:
Add velocity on the animations of the character. (it would look better :))
Some trees are in the wrong sorting layer.
The controls could be a bit improve but they aren't as bad as the people say in the comments.
Loved the frog design!!! My congratulations to the art designers!
