When you say "characters are not showing up" it means you can't create a character?
I downloaded the game from here. This is a photo of my screen 10 minutes into the game, the white circle keeps moving but the character never appears, i can move the sliders but the number doesn't change, i cannot even see the differents heads, colors... The same thing happens when i try to start a fight, i saved the character (i never saw how it even looked, nor on the editor nor anywhere else) tried to start the fight and it just won't load. (I cannot post the photo because itch.io is having problems with the servers lol)
