Hey there! It's me! In our enthusiasm during the jam, we kinda skipped the step where the game ask permission to access the microphone. If you need help doing that, poke-me on twitter or facebook or whatever (all links on narF.ca). I'm sure we can make that work on other people's computer!
Alternative: You put instruction on this page on how to grant permission manually. Otherwise, people can't play your super cool game!
