Thank you for your feedback.
But I'm not sure I understand what you mean by "extra FX on cards playing". Interaface/UI visual effects?
Anyway, I actually saw your review in our review submission form on the website. I just wanted to point out that we read it there too :)
Yeah, we are thinking about sound effects, but to be honest, it's easy to fail to implement it from the coding perspective. Bad sound effects would be a disaster. We just don't have such an experience currently.
Oh, and I saw your review about "slow dice speed". You can select an option for fast or instant dices. Just click an options button near the deck button.
