I'm going to make a wiki page for levels once I figure out what information would be useful on it. I figure notes on the general monster spawns per level (not individual rooms, because those change), as well as possible start and end locations would be useful. I'll also be looking out for variations of the floor layout, so I can record those and find some aesthetically pleasing method of adding them to the map.
Is there anything else you guys would like to see on these?
Oh yeah, because I've never paid attention, I don't know if that map is one of X variations that Overgrown Path can create, if it's just a generic map that any room can use, or if it's a compilation of random elements that are randomly assembled every time someone enters a floor. It could be that the map isn't unique to Overgrown Path, but I'll update as I figure it out.
I've seen more than one map layout for a level. Wolvers Den comes to mind. I've definitely played that map and had 2 different layouts. I'm not sure if that level was changed specifically, or if there are random elements to what a map will be laid out like.
