Thanks for giving it a try. It is challenging, and i can understand the difficulty. If i can get a bit technical when the tiles cross over the square area it is possible that a button press will go against more than one arrow. The program always defaults to the first one, but only if it wasn't previously considered missed. Say you have both up arrow and right arrow both evenly in the square (half and half). If you then pressed right it wouldn't count as it goes against the up arrow (as it is the first one that entered the area). Of course the up arrow would be considered missed and wouldn't count again if you hit right it would correctly count against the right arrow (as the up had been set to missed). I'm not quite happy with the implementation as perhaps it should consider any correct within all tiles in the area and not just the first, but i need to go back into the program and try to solve the issue.
