I simply played (and finished!) your game, and pointed out some possible mistakes; do what you want for credit or not.

The wetsuit bug was mine. Adventuron helped me to track it down. I had added two custom wear handlers, one for :match "wear -" and one for :match "wear *". The second one was clashing with the system one and I'd forgotten to add a specific wear handler for the wetsuit. Anyway, all fixed now and thoroughly tested. Unfortunately, this means I didn't have time to add the new end-game code and test some of the other changes, so my update is delayed for another day.
