Personally, I like the fact that the casino is not licensed and I don't see this as a drawback, of course supposing they can keep operating like this for too long.
I tried the games in demo mode and I noticed that the design is not well optimized for mobiles, unfortunately. You need to work on this, imo.
Also, I understand that the games are provably fair but I didn't find how or where the customer can enter his seed! Or this option is not available for demo mode?
