Hey Crushie! Thanks for all your kind words - fun fact: we actually used a Snowball mic when developing the game! 🎵 Sorry to hear that you've been having some calibration problems though D: Did you try to hit 'Esc' and adjust the Mic Sensitivity all the way up? If your computer already recognizes your mic/your mic works on other apps, then I'm assuming your Input Settings are fine on your computer.
Let me know if changing the Mic Sensitivity helps!
