I've got no modding experience and figured I'd ask. I've got pretty bad arachnophobia and can deal with the spider enemies in the game since they're far away. That splash image of the spider when you lose the game is another issue. Can anyone direct me to the steps it'd take to swap that image out with something benign? I've done some searching about how to mod the game but I see it isn't really officially supported so information is sparse and seems to rely on some preexisting modding know-how.
