I like to pick up random games on itch.io that are small and so don't have a lot written about them. But one thing this means is that there's a limited amount of context to have when going into a game. I do enjoy that experience, but one thing that makes it difficult is a lack of content warnings. 

It could help if there was an optional field for content warnings on itch.io games. It wouldn't need to be mandatory or have any complex filtering options, just a plain text entry where the game's creator could specifically note CWs that they're aware of. That way there's a place on the game's page that someone can check when they stumble onto a game. Technically any creator could do this now in a description field, but by the nature of including it as an explicit field, it will encourage people to give it thought and inform their audience appropriately.
