I think that you need to add some fancy effect for high spinning velocities, as the button at some point starts to spin so fast that it stops looking cool. Also, if it's a bitcoin themed game you can add something like trading, For example, there will be an exchange rate for dollars, you sell your coins at this price and then you can buy bitcoins with dollars when the price is lower. By the way, you can add more unusual mechanics connected with the theme to make the game more interesting and less monotonous.
Hi! Thanks for applying my suggestion, but I don't think it's noticable enough. Maybe you should change color to golden like in the old version by using a function that makes a slow color transition like gradient. I don't know if it is hard in Construct. Also, I thought about applying something like a tornado effect like in the picture or motion blur. Anyway, thanks for the update)
