I really liked this. It took a while - probably to do with the fact that I haven't played N in a long time - but despite the fact that it took half an hour, it was consistently enjoyable.
It has a really nice learning curve to it, too. Faved.
I would have loved to see that trap-doors enhance the experience as opposed to using them as an aesthetic quality. I wasn't too keen on the trap if the wrong move was made. That kind of brought the map down for me, but it was alright as is.
