set the resolution to 160x144 as well for the game window. it works for me
do black bars show up around the game view for you on itch? it seems to be something on itch's end, dealing with the resolution as if I zoom in, then the game view does upscale but it still leaves some unwanted black bars around the central view
I haven't experienced that... thats weird
might be because im using an older version of Unity, idk. Im using Unity 2021.1.20f1, that might be the reason
