The tax interview has nothing to do with a project getting indexed. The tax interview must be settled in order to get paid by us when using the payouts system, but other than that it has no effect on your page. This means that people can buy your project before you’ve finalized how you will get paid, and the funds will sit on your account balance.
I checked your account and see a completed tax interview. If you need to make changes you can email support.
It’s likely that the game is unindexed now due to the first time price
For first time sellers, we typically require a page review before it gets indexed on our browse and search pages, but your page is otherwise fully functional.
Hope that helps
