I've spent the last couple weeks working on the Replay. Besides some long overdue bug fixes I also integrated sound rewinding. It's not overly tricky code but it was time consuming.
In the video I also dropped a Varial Flip. The trick came together quickly but it's not really a freebie. I had gone to greater lengths with the Flip and Shuv physics upfront to make sure they would play together nicely when I did combine them.
