Extra gameplay features will definitely make the game more interesting. I actually have few of them as ideas, however they're scrapped due to time limits. Would definitely want to bring them back when I get the chance to.
That is a mistake on my part for not implementing a pause menu to have the settings changed mid-game. I actually didn't find the said sound hard to listen, but I think I would change it since I didn't spend much time on it. I do agree there should be an option to toggle the animation completely, thanks for suggesting that.
I myself would like to work on it more, however I'm currently in busy school weeks, so the progress would be very limited. Will want to eventually have the game be updated.
I appreciate your feedback!
