Hey! Yes, I used only picoCAD, as it was a requirement for the jam, no other tools (apart from pixel editors for the texture) allowed. I really don't know how or why the quality is different on your side. I don't know if it makes any difference, but the way I do it is just maximize the picoCAD window + focus on the render view (I have a 1080p monitor). Also does it happen to other submissions or just mine?
