I am very sorry you got stuck with the pirate, I tried to limit the possiblity as much as possible in particular by making sure you would consume rations only on empty tiles, I knew there were still some places it could happen and hoped it would not.
I am also sorry you really took the time and still did not reach the end.
If you started to fall into holes and such you probably were already not that far away from the end, there's one stairs down in the south eastern part of the third floor (the location indicated on the map) which leads to a way where you need a ration and another one in the north eastern part which technically does not require one yet the message to solve there is a bit harder to solve than the others (it's not super crooked either, if you think of something and try with the first word you should manage to solve it).
So yes, thank you very much for taking the time to play and sorry it did not fully pay off.
