Retry button

[Northadox]

If a player is doing a single player race, there should be a seamless, easy "retry" button when playing a level that resets the level to the beginning without having to redraw/rebuild it, setting blocks and the timer to how they were at the beginning. I suppose this could also be an option in multiplayer; perhaps an option to vote for a reset, and if all players participating agree to it, it would reset. This should be as instantaneous as possible to reduce any downtime between attempts; within the frame, if possible. This could be a GUI button or a bindable key. This should also skip the countdown, or have it go instantly.
It's a real pain in PR2 resetting (say if one is looking to do a good speedrun), having to exit out of the level back into the lobby, rentering the level, and having it draw again (especially in artistically vibrant levels; disabling the art isn't fun!).

Yeah, this is a thing in PR3 campaign and it's really good (although not regular levels)
One thing I think it needs though is to not reset the music, in PR3 campaign it resets the music which is annoying
