Also known as what every single ID Engine / GoldSource / Source[1] / Unreal Engine / many more engines do for records and replays, except they do it in a binary format. It's not exactly a novel idea.

True. But:

1) It isn't exactly trivial.

2) Someone who didn't play games in the 1990s, and doesn't like RTS games may very well actually have never played a game with demo recording and playback.

3) Hell, I was unaware that either Source or recent versions of Unreal Engine were capable of demo recording, and I've played the shit out of lots of games that use both engines.

In my case, it was new to me, and I have yet to see this functionality in any mobile game that I have played except for my own.

I do hope you continue to refine your demo playback techniques and bring this functionality to ever more complex games! I also hope that game devs will push hard to take some time to add demo recording and playback to most of the games they build in the future. :D
