I'm not sure if this has been suggested before, but.

Due to my game crashing a lot, I was thinking that it would be a good idea to implement something that manually or automatically saves the game data every few frames into a file that probably will look like a replay file.

This way, things like spars can be paused midway or games saved if people ping/crash, so that they can be continued later.

The saved replay could possibly be named like the things in the autosave folder, and then be shown in-game in a menu of sorts where you can customise which players play as Uke and Tori before the match resumes.

It's probably going to be difficult to implement, but I think it's a good idea so I'm throwing it out there for you guys to look at. What do you think?
