Generally I agree with all of the issues presented. But I have a problem with some of the comments made here.
I think people assume a lot when they hear 9 years of development means a lot for an independent developer. This is a hobby for the team, and those 9 years doesn't mean there was 9 years of constant development of the game. Things are constantly changed, scrapped, and redone. People take breaks for months and even years. I just don't see how someone can think "9 years for THIS?" when the game is just a fun little project for the devs. It's kind of insulting to assume the game is worth less because it tooks so long to come out.
As someone who has followed the game for years, that development for the game as it is now hasn't really kicked off until 2014 or so. Before that was a comepletely different game with a completely different name, graphics, engine, etc. Just following Gav's work on deviantart, you can see that development changed drastically over the years. Development of a game isn't just getting from point A to point B. So many things happen along the way.
This is also speaking as someone who has been working on a game since 2013. Despite technically developing it since then, I've restarted so many times and took breaks for so long. I would be really upset if I released the game and someone was disappointed in the quality purely because of how long it took me to release it.
Basically, don't ever fault a project, especially, one done casually, as not being "worth" the time it took to produce. It's awful.
