Thanks for playing and providing such actionable feedback! You gave lots of great ideas that I'd love to get implemented once the voting period is over.
We did actually have sound effects for the combo system, where a minor scale (A minor, piano) was played based on the player's current combo. We were really excited because it supported the play on words in the name of the game AND added another layer to the theme, but it ended up being so annoying that we decided to remove it last minute. We're hoping to find a better way to add polish in the future.
Thanks again for the feedback. Really appreciate it (and sorry for your fingers) :)
