Your project was published less than a day ago. It is not unusual for a project to take a day before it is indexed. It takes a bit longer for the first paid project of a creator, as that needs some additional manual review by an admin.
I would suggest to wait a bit longer, maybe an extra day. It won’t make a difference in how popular a game will be. Plus your page is already public, so you can start sharing it on other social media already.
