Most of the states look nearly identical. That would be hard spotting an imperfection in a state seal on a blue backdrop jammed into an irregular shape.
Colorado and Wyoming might not need trimming though.
I feel like the cross on Greece was too big as well. It (almost) went from top to bottom and side to side, while it's actually smaller and would still be smaller on a map.
Unfortunately doesnthe work for me on mobile, nearly all blue map with a tiny corner of grey land, no optin to get it all in view by zooming out or something. Tried desktop view but no improvement.
My phone might be a bit outdated though (galaxy note 4, android version 6. something)
I finished with less than a second because I had every country except Ukraine and all the countries were in alphabetical order. So the only European country alphabetically after United Kingdom is Vatican City, so I don't know why Ukraine is after United Kingdom, but luckily I typed it with less than a second.
the shades are off and the cross is too big. the cross (almost) goes from top to bottom and side to side, while normally it's smaller. Also on maps like these.
Consider listing the answers non-alphabetically. Once you guess three or four countries most of the others can be narrowed down by guessing countries in between.
