I'm really glad to know you enjoyed the game. On the intro screen, there's a short musical theme (very simple) that I kept at a low volume so it wouldn't bother those who aren't into that. You can try turning up the volume a bit to hear it. I plan to release an update soon with an improved soundtrack and some more sound effects as well. If you'd like to create a chiptune for it, feel free—I'd be happy to check it out. Thank you very much for your kind words and suggestions. :)
