If this happens, the game should either be a $20-30 title or contain a lot more stages. The first game was essentially a shallow arcade game being sold for full price, so I didn't buy it until it was heavily discounted (I believe I found it for $12), and it took my sister and me only two evenings to beat it.
We also ran into three times when the game just stalled and wouldn't progress, so I hope any new one would have better bug testing.
