Here’s a few things I can suggest based on my personal experience:
-
Make sure to edit your creator’s profile. Once someone lands on that page, that means they are excited to see more of your work, and currently it looks pretty underwhelming for the amount of games you’ve got.
-
I took a look at some of your games, I’d suggest editing the game’s page to look more attractive. When a user lands on that page, that means they are considering if they will invest in your work. If they see a blank page, with little effort, it’s only natural to think that the game might follow a similar path.
-
Make some social media profiles. Every time you publish something new (a medium-big update for a game or a new game altogether) also make a post on all social media, linking to that game.
-
Try to establish some kind of consistency. A creator that has been making a new game every 6 month, of increasing quality, for the past 5 years, looks way more attractive and have more future potential than someone that made 3 games 5 years ago, and 5 more games this year.
-
Try to spend extra time on the cover images of your games. By looking at the image, a user should get an idea of what the game is about, but also what quality to expect. A low quality cover signals to the users that the game possibly follows the same quality.
Apart from these, there are options where you can pay to have your games advertised, but I haven’t tried any such route yet, so I don’t have an opinion on how effective they are.
