I can totally understand this being something that doesn't bother a lot of people but the way the resolution works in this port drives me up the wall.
The way it handles turning this from a 4:3 to 16:9 and beyond resolution isn't to actually let you see more of what's going on in the horizontal space. It instead takes the lazy tv show remaster approach and zooms the screen in giving you less information then you'd normally be able to see. You can technically change the resolution to a 4:3 one but it's really only technically 4:3. It's technically a little wider than traditional 4:3, making the pixel art look a bit wider than it should. You also can't even seem to go beyond 1080p in borderless fullscreen so I really just get the impression something is just base level wrong with how this port handles resolution. All of this is ignoring the now optional "hd" Vaseline smeared blur filter, mind you.
I know a lot of people straight up won't notice or care nearly as much about the resolution but it really just makes this unplayable to me. It's a really pretty game, and I hate to see it's looks depreciated.
