I really liked your use of the game's story to talk about where you're at with developing this engine, what you want to do next, and what you're having a hard time with. it's always refreshing seeing other developers air their thoughts like this, like a public diary. and that it's happening inside of a game engine in-development makes it fascinating, because we get to play with what you talk about as you talk about it.
writing good stories and narrative games can be hard, but very rewarding to keep trying. good luck with your projects in the future, I'm certainly looking forward to seeing what you do next!
