I love line-drawing games but I have my fill of them (Harbor Master, Heli Rescue, Boom Brigade, Flight Control, Aqua Globs). I think devs need to focus more on other genres like FPS and good solid platformers (such as Mario Bros and Soosiz). The app store is already flooded with tower defense and line-drawing type games.
