I'm sure I'm not the only person who has thought of this, but I have an issue with the filter options. They're very well designed, being able to search genres, prices, and being able to add tags as you search for one thing. But shouldn't it work in reverse too? Shouldn't we be able to filter OUT things we DON'T want to see? What if people don't want any horror games in their search results? They're supposed to just ignore that variety of content? It'd be more convenient if Itch.io had a way to remove seeing those things all together, rather than risk seeing them. It's not a big issue, and yes, people can just ignore them but it's a quality of life feature I'd like to see added in the future. 

You cannot filter search results. You can filter tag browsing with a "inofficial" feature by adding a query in the form

?exclude=tg.tag-to-exclude

You need to be logged in for that and it only works for one tag.

(I actually made a buttonfor that, but it is an unpacked chrome extension)
