As a Roblox developer, I want to be able to make a game where you can slow down time and reset the game’s physics state to an arbitrary time (within some reasonable bounds).
If Roblox is able to address this issue, it would improve my development experience because then I wouldn’t have to write my own physics engine in Lua.
I support this!
The only way to do this now is to use workspace.Gravity and slow down everyone’s walk speed. Not to mention, you still have to slow down the camera, otherwise, it would really ruin the slow-mo experience 
. You see what I’m getting at? It would certainly be a lot easier to do this with just a click of a button!
Also, I hope that we are given the ability to edit this in a script afterwards if needed.
