No, that's not the issue. Even if the exit is in the corner, the snakes/dark/yeti/ufo/etc text hides the arrow until it disappears.
OH, right! I forgot about that. If I had properly thought this out, then I would have remembered - This happens to me all the time.
I think I had an idiot moment when I was reading this post, and typed that.
Yeah, I guess it is kind-of an issue then. Well, yeah, I guess it should be fixed then.
Well, if the level feeling messages hide the compass pointer, then you'd know that the exit is straight downwards anyway. If it was more to the left, or more to the right, it would appear in the left or right corner, out of the way of the text, so I don't see why this would be such a big issue, really.
