Thank you! That is similar to what perey said and is very helpful feedback. I'm definitely going to look at adjusting the language for the diagonal directions so that people don't perceive it as being absolutely literal and rather see it as a directional approximation to help them to narrow down their search.
Thank you for your kind comments too. I'm glad you enjoyed it, and that the music wasn't annoying. I worried about that a lot because it's a fine line.
