There IS music and sound effects... Not everything has a sound effect but they're definitely there.
I didn't have enough free time to implement saving, and tbh if you get it then it doesn't take long to complete. So it also boiled down to the utility of a save feature which in this state wasn't much. The stalemate bug exacerbates this though, which is unfortunate, as I also didn't expect that to be so common.
I am continuing work on the game, so I can at least promise you that the next release will be a lot better, haha!
