The game looks gorgeous despite the low resolutions. The artstyle hides it really well. In Doom the blurryness was noticable at times, but I'd have sworn Yoshi runs in HD if I hadn't seen the DF video.
I like seeing dynamic resolution utilized in yet another of Nintys 1st/2nd party titles though. If we ever do get a Switch pro or a backwards compatible Switch 2, all of those games will maintain rocksolid performance while getting a serious resolution boost.
