Hey there,
I was able to locate your game with ease by searching “breaking point”. Making sure your game is tagged with all the applicable tags can help for sure if players are looking for anything specific such as ‘Shooter’ to the genre list. You can modify these under Dev Portal in the offers section.
As for additonal ways to help promote your game;
When your game is first released it will show up in recent releases on the front page. We also do tent pole sales that you can participate in through out the year using the discount price management tool in Dev Portal.
You can see your games performance in the analytics section of Dev Portal as well.
I would also recommend asking around in the Epic for Indies section of the forum for more suggestions and guidance from the general community. They even have a dedicated marketing section
