HI basically in the title. Im using the app and Im having a heck of a time (not in a good way) trying to figure out how I search by subject. For example search for games where u are royalty. There doesnt seem to be a search feature. Please help.

In order for you to find games by some topic, there needs to be some pre-existing tag that developers have agreed upon to classify their games with. Unfortunately the one you are looking for is pretty specific, so there may not be may be many developers tagging their games that way. Here’s the royalty tag: https://itch.io/games/tag-royalty

There are two types of searches. "Search" and tags. Neither searches for content/subject. Try a regular internet search engine for that. They should accept things like

site:itch.io play as a ruler

The search box gives you title matches and partial title matches and maaaaybe some games that have terms in their short description.

The tag box gives you, well, games that have been tagged by the developer with that tag or genre. But since this is free tagging, your guess is as good as mine as to what tags would be used by devs of games you seek. If the game even has proper tagging to begin with.

If you find one, expand from there, look what tags are used. Maybe you find a bubble of games interconnected by specific tags.

I would imagine you can find some with those tags: sandbox, management, simulation, kingdom, medieval, court, king, queen, prince, princess, ...

And of course, in the search box, you can find games that have royal terms in their name. They will use titles like king something or something queen something or something kingdom and so on.
