Developing games became easier and more accessible nowadays compared to many years ago. Which means that not only companies produce games nowadays, but also individuals from home.
Even though some individuals or small teams can bring out masterpieces, they lack on other fields. A big company has marketing, support, ambassadors, community managers and many other people. Many individuals or small teams lack experiences or skills in these kind of fields.
True.
While in the case of small indie teams, it varies by the studio. Personally, I regard my current game development as more of a hobby hopping to take it further however in the end it really depends on the people working.
In the project, we are currently working it's just me and one other guy, however, we each fill multiple roles which don't just include the development side of it.
While truthfully speaking it is quite common with indie developers since one simply cannot justify paying some specific roles at least until they have both the income and need to do so.
But this isn't afcourse a excuse to go off radar completely. This is the worst you can do, keeping customers in the dark. I don't know what is true, maybe they ran away with the money and 'pretend' to search for 'extra' people as a show. Or maybe they are really struggling with manpower.
Honestly I doubt anyone will know the full truth until they confirm it.
They should have seen this coming before they started with the project. This is one of the reason's why plan making is very important when you put a project or product on the market. This plan should include everything, from hiring people, to support, to communication to even bankruptcy and lawsuits.
They are just heavily unexperienced in these kind of fields, but that shouldn't be a excuse afcourse. They probarly don't have any experienced in companies.
While it is sad to say, however a common thing I believe a lot of people seem to forget is to even make a plan at least a couple of years ago when I was just looking around joining random indie teams and learning things etc. a common thing I saw was that they just went into it with zero plan, analysis or project management and probably other things too, while I cannot say if that was the same thing here but who knows.
Regarding the later parts of what you wrote, I'd say I understand them while unsure how present game development is in Taiwan (probably way more than here), in my country, it is hard to find game development companies to even get experience in the first place. Ignoring mobile Unity when it comes to Unreal Engine as an example, there is a total of 1 company and even for them they have to hire their workforce elsewhere.
In the case of this game it would seem they want to hire a local workforce is my guess however who knows since the language barrier is always a factor.
Then again whether or not they have experience in "big" companies wouldn't have mattered that much either way since it would seem their staff are primarily just developers and lacking in other fields.
