Hello,
Hanabi is my most favorite game on BGA. But I am not a big fan of new look and interface. Yes, you can say, the graphics is now modern, but the old look was simple and everything was very clear there.
Only pros I see are:
1) Big numbers on cards
2) "Black powder"
But then the cons:
1) Giving the clues takes so much time, the game gets slower
2) Discard overview is too small and is not good to recognize the colors (mainly green vs blue), same with clued cards (numbers)
3) Players who are playing Hanabi on BGA only will not be familiar with "table look"
4) With more players, when you want to see all the players cards, you have to unzoom and everything gets too tiny
5) Bomb tokens as picture?? Why ??
6) Clue tokens - I think on left should be what you have left, and on right used clues (then why black / white background?)
To be honest, I have played 4 games only with new interface. First was with experienced players and was very slow (maybe due Black powder, but anyway), the rest ended up before end - abandoning. I am unhappy
