You should make the board spinning optional, and not clear the entire board with a wrong click. I just left the game because every time I'd click wrong, the whole board disappeared.
It's just not a fun mechanic to remove any progress that I've made the moment I guess wrong. I'm quite literally getting punished at random, and that's going to drive away a lot of players.
As for the audio, there's no pitch shifting. Always add that to repetitive sfx in a game, or it gets annoying fast
