I stuggled to understand what to do at first, but when I used the first butterfly to blow up some hay, that was a nice aha moment. The movement was a bit frustrating and I got stuck on the first level.
I love the art and that there are actual frogs and butterflies in the game hahaha. How many levels did you make?
If you make this more responsive (A little faster movement) and explain things in the game a bit more, this could definitely go on the Google Play Store and I'd also be willing to play again.
