Your profile is not my home page. Nor is it the home page of your customers. Going back to your home page does not make much sense. We are browsing Itch, not your subdomain.
Also, people do not start on that page. There are no pages that link to profiles. The browse and search link to projects. And from there you can visit the profile if and only if the project's developer has more than one project. There appears a View all by ... button next the follow button.
Also, what do you mean with two bg? One is a banner and the other is a background and both your project's themes and your profile theme have that.
