heyo! I actually really like this mod, i think its a really wild way to play Nuclear Throne- I actually made a portrait or the character!
i got it workin' in game too though Esau is cut off a bit- its not perfect :p
If you want, you can use it in the mod, just make sure to change the sprite dimensions in the gml file!
global.spr_portrait[0] = sprite_add("sprites/portrait.png", 1, 20, 310);
that seems to fit well, but feel free to experiment with it if you want!
(I can probably send u high quality versions of the sprite elsewhere if you need too)
