Horrible controls

The game is good but the controls for touch screen is horrible. I dont know why they dont have visual buttons to press but instead I have to move my finger up and hope to god that I did it right otherwise your character falls off a ledge. Not sure how many times I have figured out the puzzle, but need to continuously retry each section just because of delayed response. Thanks for stealing my five dollars both to limbo and the apple market place
