Small patch to 1.4c, concept art and outlook!

First of all, this patch fixes three minor bugs.

While the game page has been quiet, I have been working hard on the game since summer! A big update is in the works. Among other things,   a sort of minimap will be added to the game, that will let you quickly find unsolved puzzles. I expect this feature to be finished within a month or so.

I have also been working on the long term prospects of the game. To that end, I have produced the first piece of concept art!  It shows how the first level of the game might look. Thoughts?
