Yeah, there'll be more feedback about how the techniques worked out for you. We're still trying to figure out what the best way of presenting the information is.
Having things fully working as-is, barring future improvements, is going to be as much as possible our approach from here on in - we did have to do some rapid prototyping early on which led to some of that "insert working stuff here" scaffolding that you're seeing. In my experience in software development in general, you shouldn't push out half-baked things - either something is done or it's not done, and if it's not done, users shouldn't be seeing it. It's a good rule of thumb in general, and in a future project especially, but even as we continue on with this one, we're going to try to apply it.
That said, if we don't have any placeholders, it becomes nearly impossible to tell what direction the game will be moving in. If we had started off with only techniques that had their underlying systems implemented... well, there would be very few of them, and you wouldn't even see the stance system working at all. We're going to do a ton of iteration, and if we had things our way, we wouldn't be showing development this early to anyone... but that's also a lie, because the only reason we've been able to get as much as we have done has been because of feedback, positive and negative, and support that this initial roll-out has (somewhat unintentionally) brought us.
We had actually considered retreating out of public view for a while to release a "public" demo once we reached version 0.2.00, which would be at that "everything is in place and we're fleshing things out" stage that you mentioned. That was our original plan once the game jam was over, but we were pretty surprised by the response we got, and were seeing a lot of people that had come to expect the frequently updated public builds.
It's hard to say what approach will work best - everyone has a different expectation of where we are in the project, which is understandable, but if you think we're at the 90% mark vs. the 20% mark, you're going to see a very different game. I think it would be good if we put together a roadmap, and we've actually started to post pieces of that on our Patreon page publicly; we might compile it and flesh it out and post it as a sticky here in this forum, so that those who are interested know what to look out for and expect, and, if something is missing that they think should be in, to have an opportunity to let us know about it.
I will say that we are learning a ton from this, and as we center in on a more defined plan for this project, we're also keeping it in mind as a template for any future game projects to come. :D
