The app needs a little work

Nice collection of puzzles. The issues I have are with the app. 1) It should work in landscape mode. 2) I want to be able to turn off the dots that appear when I select a piece to move. 3) There is a noticeable delay when I make a wrong move and no delay when I make a correct move. Its distracting. I would have a fixed delay after all moves.
