Poor location for hammer
I prefer the FlipPix Art puzzles that have the hammer at the bottom of screen & paintbrush at top (like in Country Life) so there’s no chance of inadvertently tapping the wrong one. However, the fact that the location of the hammer is different in different FlipPix art puzzles makes it difficult to switch between puzzles because you get use to hammer in one location, then on a different puzzle it is in a different location. I wish all the Flip Pix art control buttons were in uniform locations from puzzle to puzzle.
