Oh sure if I finally finish a clean doc, I'll send it to you ! It'll be in French tho, and I'm not sure I'll translate it to English (might be a good exercice to try but that could be long...)
I actually tried several codes on your game, hoping I could get over the sea at the end (or, what I'm seeing as a sea). I love how it is reminiscent to Dwarf Fortress in how you can imagine landscapes, or any other kind of environment ; I saw you were describing it as going under because the player can use ropes and ladder, but I've played it without reading the description and can't unsee it as a top down explorer on a world map, with bridges to place and ladder to go over ponds (in Zelda I fashion). And I actually like that it can be viewed in several ways.
I'm going to try some other codes just to see. And I might try a similar experiment if I finish the TTRPG fast enough. Also I did not encounter the DLL problem for now.
