Yeah, the game is still very much incomplete. It's certainly polished and you might not feel there's anything missing when you play it, but there's still lots of important features and content missing.

Obviously the missing content is what you'll notice most, you'll get to a point where you can't progress further because it's just not there yet. This could be a problem if you just want to play through the game properly once, though it is designed as a game to play multiple times with a strong focus on core gameplay, which is very dynamic and a lot of fun, once you get past the very steep learning curve.

Well, that's certainly not why we're doing it, we'd love nothing more than to release it this very day, if only we could. The content beyond what's there now is quite different and we're still completing some features to support it. I think I can safely say that we suck at all things marketing, it's something we don't concern ourselves with, and we're often criticised for it.

Well, I can't speak for the Games In Development platform specifically, it's my understanding that GOG hand picks the games they want to feature. Of course this cannot be a guarantee, anything can happen and you should probably only get the game if you think it already offers something you want or you want to support its development. The latter is what I consider to be the purpose of the platform.

On Steam any game can be greenlit by the community, and the Early Access platform has a pretty bad reputation due to some games that are never completed or don't deliver what the players expected.

In our case I can say that we've gone beyond our original goals in response to feedback and the community in general. In many ways the game offers more now than we originally promised, and it will go far beyond that when completed, but it's not there yet. Considering this any date we would have set would have been meaningless, and although our goals are now quite final, we still don't feel we can give an accurate date, so we don't.

Our commitment to seeing this game completed is absolute. We are for the most part a small group of childhood friends who have shared this desire our entire lives. There is nothing we want more than to make this game, nothing. This is truth a prelude to our larger and even more ambitious game project, Sui Generis. Everything was developed entirely from scratch exclusively for these games, the amount of effort that has already gone into this is enormous and we work tirelessly to see it through.

There was a time when publishers gave developers creative freedom, supported diverse and original games and didn't enforce greedy and exploitative business models. That's what we grew up with. Platforms like Kickstarter and Games in Development can be risky or even abused, but they also give developers who aren't already established and able to fund their own projects an opportunity to do something that is born of ideas rather than established trends and A/B testing. We were offered publishing deals, but if you're passionate about the game you want to create the "minimising risks" and "maximising profits" conversation is one you really don't want to have.
Oh, definitely this year. If I had to give a rough estimate I would say the game will be almost entirely complete within 3-4 months, but some non-critical features may not be included at that time. Examples of this could be co-op multiplayer and some forms of thaumaturgy (magic). As it is we already have a tonne of stuff lined up for the game that however requires a few more features to be release ready.
