It's okay, but it could be better. For one thing, the physics of the frog aren't very good. It's an interesting idea, but I don't like the jumping and how you can't really move very far, while you jump quite high. It throws you off balance and makes the game harder, but it's not harder in a fun way, it's harder in a frustrating way. Annoying jumps and making it incredibly easy to fall right back to the start aren't really substitutes for a fun challenge. I would also make the text on the platforms telling you what to do have a black border or something like that, since it's kinda hard to read white on light green.
