Did you play on iOS? There is an issue with godot, that the sound gets turned off, when your phone is in silent mode. And really, we did voiceacting for 25 characters, the sound is a big part of the core experience ;) Thanks for playing.
No, I played on Windows 11 and using Firefox. Other web-games I have tested had no issues with the sounds so far.
I will need to test tomorrow with different computer if I can then enjoy the sounds too!
