Actually in my opinion the game was a little hard but that's surely just because I'm a noob. I really like the leveldesign, but as a tipp you should only use pixel OR vector sprites. And maybe you could make it that you don't have to hold down the right arrow key the whole time because there's just one way to go.

cool game. Could make it little harder I saw the frog only at the start.

Some more biomes would be fun
