This has a great style and has evolved nicely.
But I think the setting has evolved away from the frog, or the frog hasn't evolved with the setting
as in, if I hadn't seen this gradually improve, I think I'd be wondering why it's a frog and not a human or something.
However, I think once you show some real level design, cliffs, water, etc, it will be better.
And the animation.. I think you're missing out on a good opportunity with a frog character and human animation, I suppose because you're aiming for a more traditional feeling of control, but I think something more frog-like (as BB said) would be neat.
Somewhere between this, and the frog in Donkey Kong Country would be perfect I think
can't wait to see more
