The problem has already been fixed 😊 Incorrect SID configuration on the VICE emulator 😉
I just upgraded my VICE from 3.7 to 3.9, and I now here the repeating audio. I will try to see if there's a fix I can apply. I never had issues with VICE 3.7
I turned on your game again on the latest Vice and actually listen to the repeating sound again 🤔.
Nevertheless, I would still like to offer a physical release of the game by K&A PLUS 😊 Check out our website and email me.
