I'll try to look into the unregistered inputs, but chances are you clicked accidentally with a mouse or a key that made the game lose focus (ex: alt or the fn keys).
As for the online play, I'm still studying how to do that. I can't guarantee that it will be implemented but I'm trying to squeeze my brains to add that to the game.
For now though, my focus is to add improvements, most of which are suggested by you the people. Hope you stick around for the next update, it's going to be a major one.
