I think that is a very good description. It certainly is a depressing robot. I agree that sometimes (or even most times) it is difficult to spot the right answer. Partly this is because some answers that are too ambiguous. The GUI works fine on my computer but I haven't tried it anywhere else. Probably the positioning should be done in relative numbers instead of absolute. Anyway, thanks for taking your time to comment and happy you enjoyed our little game despite the shortcomings.
