ZOOM FEEDBACK!
The menu texts and some sprites appear smeared, at least when the game is not on fullscreen, resolution is 1680 x 997.
Please click/fullscreen the 1st screenshot to see the difference. The preview smoothens all, including sharp details.
Also, this huge screenshot - > https://imgur.com/a/tsbW0MS . The difference can be seen if you download & open it on a fullscreen.
Sorry, I knew you somewhat aware of the issue, I just want to pint out it may bleed to some sprites too.
