I rescued both princesses on default difficulty.
I love the overall silliness. Catching and throwing the princess, and potentially losing the princess and leave empty-handed, are hilarious and everything about the horse (that it talks, the animations ...) is too. The visuals are perfect NES graphics too. And what's cool is that all that is not wasted because the game is very fun too, the controls feel good and the difficulty is perfect for the jam to me.
Great game!
