It's funny how he calls himself a one man team; trying to compare to confusedape who made Stardew Valley. Only difference is, Confusedape (IIRC) made ALL the art, music and assets for his game - if not all then the vast majority. He didn't rely on volunteers to do his work for him. He also didn't whine about emails constantly. Yandere Simulator is anything but a one-man team. He may be the only programmer out of his own incompetence and refusal to co-operate, but he sure as hell is getting a lot of unpaid art done for him. Last time I checked, animation and art were a big part of making a game, especially one trying for an anime aesthetic. Ridiculous.
The fact he's reaching for other established devs to compare himself to rather than setting a bench mark for his own effort just proves that he's only in this for the ass pats.
