I think R should be reload and restart would be an option in a possible pause menu that would open up when pressing ESC. There is a bit of a mouse problem where moving the mouse in-game acts as an actual cursor so moving too far to the right, left, top, bottom, etc, can result in the cursor going off of the game screen. However, the pause menu should turn the mouse into a cursor where options like a restart button and volume meter would be.
For a more an intense update that more take a bit longer, I think that there should be a feature that puts players in a range of 10 levels maximum from each other play together instead of levels being spread out.
