Hi Ofihombre! Sorry that the Music & SFX don't work immediately for you - it's likely an issue with PICO-8 in your version of Firefox. You may need to play in a different browser to avoid that issue in the future. Hope you still enjoy the game!
Hey Miles! I think the issue may be fixed; some browsers don't allow media to play audio if it's set to auto-play. I've adjusted my games to require users to press 'play game' before starting, which seems to have fixed the issue (at least on my version of Firefox). Hope it helps on your end!
