So I'm aiming to not address the past, but I'll try to respond to this as best I can because I understand what you are saying 100% and your frustrations.
First, the project itself was never really fully fleshed out. From the get go we had "ideas" but nobody pressed the ideas, they started to build a product. This is a super classical move that sometimes works but often does not. The game was supposed to be big, but back in the day none of the story for that "big" existed because nobody ever said "so what do you mean by that??"
Now, the team is getting clarification. The concept of "just do something and it will make sense later- maybe" is not an option. The team is doing tremendous work to ensure that these systems and ideas and stories are thought out in advance of the team randomly engaging with something.
For Vlad, or even anybody on that team (and most developers on this site in general), being a game director you support or believe in... I don't know? What you're asking for here is "why doesn't this team of amateurs who are making a porn game for next to nothing not treat the project like a AAA project and they don't have the same level of internal processes and controls that Microsoft or Bethesda or Valve has???"
So I spoke to this previously and I'll reiterate: the reason you're not seeing this level of professional behavior is because you're not dealing with a professional development studio.
You'll probably never get that level of service or confidence that the project will fulfill 100% of what it aims to do. It's impossible to promise that, and all that can be promised is the team will aim to consolidate and reduce scope as best it can in the hopes of delivering a complete and finished product.
This is the best you can hope for from really anybody, including major studios. Projects fail all the time. Like 99.9999% of the projects on this website, it's amateurs with a dream running the project behind the scenes. Nobody is doing this because they are cashing in for a second Ferrari.
The team is learning how to handle professional concepts and processes, and doing good at it. None of it in itself is difficult, but it definitely helps to make these future deliveries better and also improves the level of communication and messaging you're going to get. With improved project management techniques, we're able to have this conversation now. Due to improvements across the board, you have the information you need to make comparisons against older vague intentions and well documented focus and a roadmap.
rpg mechanics and platforming are negotiable. Is it more scope? Definitely. Is it going to be tuned to be the perfect system full of unique and new gameplay where untold hours were put into it and it challenges final fantasy for a battle system? Of course not. It's going to be stats, and random dice rolls based off of adding those stats together, and an HP bar will go down. Along in there will be some extra pieces to try to make it more tactical, but you'lore not being sold the next coming of rpg battle mechanics here.
The platforming will involve climbing a ladder probably, and jumping over obstacles. There is no intentions of becoming a precision platformer full of speed runner level tweaked mechanics. It's going to exist simply because it's a basic navigation piece and it's addition isn't going to tremendously increase scope or make building maps needlessly complex.
You're looking at an rpg game where porn is half the game, but you can shut off half of the game if you don't like porn. The non-porn side is not going to get bigger or smaller based off of that.
I hope this makes sense to you. This is the reality of the situation. Ultimately, if your expectation is that you demand a level of experience, excellence, and planning here that a AAA studio comprises of hundreds of professional developers who make close to or over a 6-figure incomes can do... you're never going to be happy with this project. It will never meet your needs or expectations.
On the other hand, if you want to support a tiny team of people who want to make a furry porn rpg that's not rpg maker and doesn't have the polish of final fantasy, and your expectations are more close to reality that you'll likely get something slightly janky but has a good story and good porn and events in it, then this may be something you'd like! And the team looks forward to interacting with you and collecting your ideas to help make the best furry porn rpg they can try to build!
