Thanks for your comment; so sorry it took so long to respond, but the last couple of weeks have been very busy.
Regarding your question, not much. There is an escape hatch, which is your objective, though it only leads to another, slightly larger, maze (which starts as 5×5 but originally planned as 16×16!). I had wanted to add a key or coloured levers to unlock the hatch, but I ran out of time; much as there was a day added, I needed to focus on other things, unfortunately.
Clearly, the movement scheme was intended to disorient (and took more programming than an NSEW scheme than might be apparent). Though now you mention it, I think I recall playing a game before that might have used an FBLR scheme.
Looking forward to getting some time to play your games. This whole jam was a fun learning experience.
