There was no sound for me
Chrome is supported but it needs to be running a recent version (80+). I understand that some Chromebooks become outdated and no longer receive updates. Real-time synthesis is also an extremely CPU-intensive process, so it might not meet the hardware requirements for this. The desktop app bundles up the game with a supported version of Chromium. Let me know how you like it when you have a chance to experience on your PC. Cheers!
