It's not all that bad...
You're probably puzzled by the flop of the sequel when shopping cart hero 1 was so well received. The simplicity worked then, but since that game other games in the genre such as toss the turtle and hedgehog launch have incorporated a lot of depth in their games esp in terms of development and upgrades.
So too bad for you I guess, people expected the quality of toss the turtle (which was frontpaged for so long), and this doesn't quite cut it.
