Hi welcome to forum! This looks good. I think this is one of the unique gambling game here in the forum, I am fan of strategic games let me try this out since there's a free demo on your site. Just want to add some suggestion on the graphics probably a mobile support and a full screen is a good thing.
I taught since you said you want to add something difference, it is going to be the errors you found on the platform, i a normal bases the graphics of the platform is good to me i not found anything complicating to the site because it takes me time to go through the platform verifying the scope of this one after the other but no errors, but i can not condemn your observations
