owen,
My thought is that you didn't put much effort and thought on the gameplay, and didn't play test much. It's ok to admit that.
There is also the possiblity you made such a unique and brilliant gameplay that not many people can understand or relate, but I don't think that is the case.
So which is it?
Also I don't blame you for not putting that much effort(if that is the case), because it's a 1 dollar game. Though you must understand it's a bit frustrating to see a game that supposingly the developers didn't put much thought of the gameplay, but is very succesful due to the excellent art.
However, there are worst things, like Angry birds, heh...
