I don't share the excitement so far (I've had the frog guy for an hour or two), because I find the game to be so extremely generic. The level design is never interesting, the gameplay is very unoriginal and doesn't have anything fresh going for it, and I can only play in 20-30 minute doses because it just doesn't captivate me.
I've heard the game will pick up, but so far, I suppose I'm just the type who needs something creative and new in my game experiences, and this game feels like one of the million average 90's platformers, but with nicer graphics.
Maybe I'll change my mind soon though, who knows!
Frog form is when the game clicked for me. If frog form isn't doing much, I don't think the other forms and levels will either.
