I know that the whole point of adding NotEye support was to create appealing experience and add beautiful graphics into the world of roguelikes.
Well, at the moment it is appealing and beautiful only before the moment you decide to resize the window or go fullscreen.

• Fonts are not scaled well, symbols are blurry and their native height/width ratio is not respected. (Note that once you resize the window it is quite hard to return everything back!)
• It constrasts a lot with sharp and clean tiles and also with the game menu. (BTW do not resize the underlying picture in the game menu.)
• The game does not use capabilities of modern monitors well and keeps height and width fixed in characters. This problem can be see in the inventory page: if there would be more lines available, we would see much more items. Reading the manual will benefit from more lines as well.

Size in characters should adapt to window size. Characters itself should be as sharp as tiles.
