I'm pleased with the site outlook, it has a classic look and the dark colours are not interfering too much with the gaming visual and because of the choice of colour scheme it gives you the feeling of a combination of Roulette and Dice which I think works well.
I haven't tried out the games yet mainly because of the faucet not being available as I usually like to test the waters first, maybe this is something you can consider as feedback.
Yes, the dev of this site should at least provide a faucet where a potential player can use to test the features of their gambling site. He can give at least enough for testing and playing so players can get the feel of using your site.
