Yeah, I love Pico-8, and I haven't had sound issues with other ones on Chrome either. It's unfortunate, because I really wanted to use this game as a source.
I'm taking a 'video games as an art form' course and we're doing a whole week dedicated to you, your book and video games as poetry right now! It's great. :)
PS. Is there anything you'd want me to share with our class tomorrow? Like, if you were there in our class, what's the most important thing you'd want to make sure we know about video games as poetry? (Not to put you on the spot!)
*Edit - I just sent you an email through your website, I don't want to clutter up your comments!
