I really like the UI appearance of bch.game, it's very light and attractive but what's very uncomfortable in my opinion is the font of the chat feature is still very large, very uncomfortable to interact with other players.
This is a fantastic observation. Something I've noticed over the years is that most casinos make the chat box too cluttered or chaotic to really encourage discussion, and some just make the chat font too big or allow clunky gifs and emojis that take up too much screen real estate.
I went ahead and looked at the chat box feature for a bunch of competing sites and found that [in my opinion] Roobet, Stake, WolfBet, and best of all, Bustabit have all done a great job at creating conversation-inducing chat boxes. If BCH.Games decides to tweak the chat box, those are the sites they should be drawing inspiration from.
