Could a replay feature be possible?

So devs, I just wanted to know, would replays be possible for this game? Like, could they work? Because if they could work, I definitely think it would be worth investing time into them. As somebody who likes making YouTube videos of this game, I always have an empty feeling when I do some epic/crazy stuff that nobody will ever see (My computer sucks so I can't record myself playing online). I completely understand if this isn't possible, but if it is, I think it should be pretty high priority.

That would be so awesome!
I'd have about 1000 replays by now :V

Yes this would be awesome!
