I’m not sure where you got that I would play all of the games, but the feedback stream will be March 28 at 1pm ET, and the details are on the jam page:

During the ratings period, Retro Indie Josh will live stream feedback on his Twitch channel.

• Games must be submitted to the stream before it begins (a submission form will be provided on Discord)
• Otherwise, entries will be selected randomly to reach about 10-15 games
• This stream will also be available as a VOD on Twitch and posted to YouTube
