Just visited your site and these are some things I noticed .
First of all , design is cool but rolling dice takes too much time ( Many users won't know how to switch it off , the button is at the right but  there is no label to it  ) .

The leaderboard takes too much time to load , I am sure its not my connection problem . Look into it and it would be good if you consider adding Tipping system .

Level-Up faucet , I don't think it matters much .
