I like to browse around the free adult game scene every now and then,  there are a couple things that make it very difficult to find anything new or interesting in that space:

1. Broken web-based versions of games that they're only updating the download-version of.  I'm searching specifically for web based games that I can talk about, because I want to be assured that everybody who has a browser can play them.
2. Web-based demoes for paid games mixed into search results for completely-free games, with no indication of them being a demo in the title or thumbnail, and no way to filter them out via search.
3. Older games showing up at the top of the list when I click "Last 30 days". 

I know that "Hole House" and "Anomalous Coffee Machine" are older than 30 days.  When you try to play the browser version they straight up say that the browser version is broken or outdated and that you should play the downloaded version or go to patreon or steam to get a paid version.  These shouldn't be showing up at the top of a search for recent, play-in-browser, free adult games.  They should be relegated to a search for paid games with demoes, and definitely shouldn't show up in a "Last 30 days" search.
