Super Stream-Bara on Steam
store.steampowered.com
CAPPA, a hero from capybara legend, needs your help! Your mission: free every capybara in the world from the evil clutches of Cappyland. But wait... who is that mysterious Stream-Bara lurking in the corner of the screen?

No actual livestream in real life, just one in-game. Including what would typically be the results of most streamers modding their game for more interactivity: the viewers can vote to change things up in-game for you. Does have actual features for people who really are streamers in real life, so streamception?
