To me Ketchapp is pretty much synonymous with "easy to learn, easy and fun to play, nice clean graphics, addictive, and you can play for 60 seconds or 60 minutes and have fun." This game fits right in there. It's my favorite basketball type app ever. I really love the different modes (make more please) and that the different balls you earn are so cute and often actually feel and function a little differently from each other.
I love that these games are not only free, but the ads are not obtrusive and in your face. The game does not relentlessly hound you to write a review, which is why I'm writing one (besides the fact that it's a really fun game that deserves reviews).
I see some other reviewers complain about the physics, but that's not been my experience. This is the best "flick" style game I have. It's sensitive without being overly so- you have an amazing amount of control.
I really hope they keep developing this one- I don't see myself getting tired of it anytime soon.
