At the bottom of that page on the Miscellaneous category you can find a sheet called "Win Screen" which has an interesting icon. You can notice some orange squares at the right side of it, which led me to believe that the icon was screenshot from a Cuphead fan game made in Scratch(a web browser game creating tool for kids to learn programming), but when I saw that orange square next to a grey box at the bottom of the sheet it pretty much confirmed that it is indeed some Scratch game. That happens because in order to show text or numbers in Scratch(the so called "Strings"), like on the UI on that icon, the text will always be inside a square orange box. Sometimes it can be next to a grey rectangle like on that sheet, but sometimes it's just the orange square by itself.
Edit: I looked a little more into it and it seems like the sheet itself was extracted from the original game and it's just the icon that's using a screenshot from a fangame, fortunately. I realised that because the image assets that Scratch games uses have a very small and cropped resolution(the max it can be is 480x360, I think), so if the submitter had submitted a sheet ripped from the Scratch fangame the images would be very small in resolution too, but you can notice that most of the images on the .zip file are indeed very high resolution.
Still no idea why it's using a screenshot from a fangame as an icon tho. :p
