My device would lag if playing but I could watch e.g. on discord's screenshare to add my opinion, thoughts where to head or maybe bugs that get discovered meanwhile? Same as typos or searching where it's not supposed to have the player exploring (collision with objects), so it's easier to see without lagging but taking an eye on features or what I'd expect in-game?
Will discord still have just a friendsrequest-button with no text to send or could people pm you without being in each other's friendslist or having servers in common?
