Great games, UI needs improvement

Games themselves are great. The user interface is not perfect especially for calculator computations and tracing a path. Numbers could be much larger and so could visuals, most of the screen is wasted. On something as small as a phone thats an issue. I struggle pressing the buttons as Im intending to press sometimes because I have larger than average fingers and you are rushing because its timed. The combination is slightly frustrating. Also mid game Im sometimes find myself at Einstein which is probably my fault but hes to close to the buttons needed for game play. Also not sure what the point of Einstein is, slightly gimmicky. All and all good puzzles.
