I think the fact that you already implemented the expression changes is impressive in its own right, and I would imagine that you'd only become more proficient in and capable of handling more complex processes like Live 2D as you develop more games. We all have to build up to somewhere, eh?
There's no need to apologize at all, as you definitely didn't ramble! Your enthusiasm for what you're doing really is quite heartwarming. Thank you for the kind words, as well! I definitely have several game ideas drifting around in my head, but I just need to get off my lazy butt and get to work! (Or maybe not, since I would still be sitting down while I work... the phrase is a bit ill-fitting for this particular scenario, but you get my point, haha.)
It's lightheartedly funny how this series of messages has generally consisted of us taking turns thanking the other person, I must admit. I won't contribute to it much more, I promise, as I fear I may be creating some sort of infinite gratitude time loop, but I would like to thank you for these brief interactions, as a whole. I already knew you were a good game developer before, but now I know that you're a good, kind person, as well. My apologies if that was awkward or anything of that sort; I just sort of thought you deserved to know that. I'll leave it here on my end, as I already feel like I've been rambling myself; keep doing what you're doing and making great games!
