I understand your concerns about building trust, but I believe that with the right approach, your website can be successful. Building trust takes time and effort, but it's not impossible, and the best way is by providing value. Additionally, making your site more appealing by creating a better UI design and other user-friendly features will help improve the user experience and make the site more appealing to potential players. You need to make sure that your game is fun and engaging, and if it's not, then consider making some changes. There are a lot of things you can do to improve the user experience. Have you considered some themes that might make the experience more interesting? For example, Pirate Treasure or Dragons Chest could work well. Or maybe even the Heist of the Century. These are just a few ideas that I came up with, but there are many more.

But at the end, it's your call and your decision will be the best for your project. I hope my suggestions have been at least somewhat helpful to you.
