Sometimes, when I'm trying to find a new needle game to play I have to search through some pages of reviews till I find the "Needle" tag. I think it would be great if we could just have links to all of the fangame genre tags and some other popular tags on the front page so people can just click them or type them on a search bar for tags. And talking about tags, I think it would be cool to add the "random game" feature for each tag.
Oh, and I think that adding the option to just find games with only a tag in particular would be cool too. The reason why I think this is a good idea is because there's people who are avoidance-exclusive players that I'm sure they hate when the game they're playing is "ruined" by "boring" or "bullshit" needle, or needle-exclusive players that just don't want to have to deal with avoidance fights/bosses, etc.
You can click on "advanced" in the top right corner of the website. You can then search by tag, and if you press "I'm feeling lucky!" you get a random game with that tag. You can also Reroll when you get a result you're not happy with.
edit: Having some kind of "exclude" tag could be good yes. So people can for example search for "adventure", but exclude "trap" or what you mentioned with Needle/avoidance games.
