Yes, it's either EvaKiss or EvaKiss's boyfriend.
It's not essential to know but kinda important. Everyone refers to EvaKiss as she/her, and that it reflects in the game. If a girl says she's a man on the internet, it's to protect her from the simps. But when a man says he's a girl, it's to attract simps.
" she's been part of the games I've made in some way or another, sitting on my desk while I worked on GGGB and ORS. " Is what he said, so I'm assuming this picture is one of the times he took his camera out to take a picture of his cat hugging his arm while he's working on GGGB and ORS, and not his boyfriend working on his game for him lol. I'm basing it on context clues.
Yes guys will simp if they think the developer is a woman, that's why homie has so many white knights. I dunno if he ever said he was a woman, more likely people just assumed it because he calls himself Evakiss. Maybe he's trans, or just identifies as a woman? That's valid.
What interests me more is because we know he is a man I like to think about his thought process in creating his characters. Since creators put a little of their lives into their creations.
Either way I'm referring to him as EvanKiss, from now on.
