Replay value is low

I bought the full version and played it. The game is too easy. I think it requires a little balancing work. All I did was including all combos in the tower and I get almost infinite income. Game mechanics such as quality and stock in each store doesnt really make much significance. Id say it is a good time killer game, but the replay value is too low.
