I would love the opportunity to commentate for the Tetris segment of your event. I have done over 100 hours of live online commentary, primarily casting NES Tetris, Tetris 99, and Crypt of the NecroDancer tournaments – I also play these games at a competitive level, myself. I stream to Twitch twice a week, and have years of experience speaking to an audience over the internet. Feel free to request more information or examples, if desired.
