I enjoy Dungeon Crawl Stone Soup played in the terminal with ASCII graphics. I wonder whether there are other hidden gems out there which don't get attention because they are "ugly"?
I have had some people refuse to even try Baba Is You, because it looks ugly.
I had The Hex a few years even installed, so I have tried it, but only after getting familiar with the style of Daniel Mullins' games with Inscryption I pushed far enough to get interested. Still very clunky, but worth it.
I love both the style and soundtrack of that game. Maybe it's a little too "lowfi" for some people. That's the only way I can imagine someone not liking it.
