Great to see you back! I'll share my first impression.
The first thing I noticed was that my email address isn't allowed to have uppercase characters. I don't think that limitation is necessary.
my balance not reflected when I got won and lost, running 15 minutes my balance still 10032 sat.
This bug is still around: after a few bets, my balance stopped updating until I reloaded the site.
When I click x2 a few times (and my balance is 0.00000074), it tells me Maximum bet 7.4e-7. If I click 1/2, it still shows Maximum bet but now displays 3.735. When I click Roll, it still bets the maximum so it's only a display bug.
The total faucet amount that people can claim each hour is 4 USD.
Great thinking of limiting total faucet cost
I am not a designer, but i think 0.04 btc is quiet enough to get a nice avatar/logo and signatures for all ranks, maybe even less. By running a contest, you invite scamers, thiefs, and less experienced designers to take the chance to win the contest. Why you chose this method? I can't really figure it out.
Good designers are waiting for you to contact them, no one of them will join this contest.
I've seen
great results from a similar competition in the past.
I'm confirming "Loyce" in chat is me
Good luck!
