Bug/performance report:
"Your stats" on the Bet page reports the "total profit" incorrect.
I placed 17 bets with 10x multiplier, of which I won 2. The report has my profit as -13, [games won]-[games lost]. Should be +3, [GG won]-[GG lost].
Sometimes there is a significant delay when pressing "Roll Dice" before the page updates (5-10-15 seconds).
I could only manually edit the Win Chance%, not the multiplier. When trying to edit it immediately reverts back to previous value.
Other than that, everything so far has been smooth. As many others have also pointed out, I like the minimalistic design.
