Over the years, I’ve found these suggestions for how to get your game noticed: both who/how to reach out and making a presskit.
Check out Games Press for posting press releases. Make sure you have a presskit so interested journalists have screenshots and information.
Some articles to help with writing your press release:
If you follow any industry news or gaming websites, then you should keep track of which people like games similar to yours so you can contact them directly about your game since they’re more likely to be interested.
Check out something like presskit.html. It’s like the old presskit(), but as a static site so you can host for free as Github Pages or any other hosting site. See The blueprint for building a press kit for a thorough presskit explanation.
