This was a brilliant game! (Video below if anyone's interested!) The puzzles were well done and really well integrated into the game! It was super fun being in control of the 'stream' and seeing the funny reactions from the 'viewers.' It was all executed really well and the atmosphere, feel and look of the game exuded this mysterious and dark tone which went well with everything.
Also not sure what the one star meant, thought it meant other endings were there but didn't find any.
Only suggestion I would have would be to make the streamer say something in response to the viewers or some lines that the game might detect the player typing; that would add that much more depth to the game, but I think the silent heavy breathing streamer adds a layer of mystery as well!
Love the FeedVid series you're making, it really is different and fun from other game and you've done a really swell job of integrating puzzles into the core gameplay! Great job and good luck for future projects!
