So, when your making a replay, and the hit didn't DM, you will have to press "R" and then "E".
I think it would be much easier if you just could go a few frames back, insteed of
pressing "R" and "E".
I think I should bump this because it is a really nice idea. Also, I thought it would make even more sense to add maybe a button which will reverse all the actions made (space, shift+p, p, [maybe even ghost?! nah, too complicated]) while held.
