Why would it be abandoned? Because you feel updates take too long?
Maybe it's because it's a small team working on it in their spare time, doing the best they can?!
To be fair. If you're looking for a game with more regular update, you might need to look somewhere else.
Currently the amount of spare time
Porcus Dev spends on this game aside from his day job is really a lot. Sometimes I worry a little, because working on the game till 7AM after finishing work seems unhealthy to me.
But it doesn't really matter how hard you work, there will always be someone saying it's taking too long. I just hope they're saying this because they're looking forward to more content. I you're not, then what the hell are you doing here?? If you don't like the content, just play something else... there's soo much out there!
Well, no... it's not easy. But that doesn't matter... it's like this because a lot is tied to the main storyline.
Also... a lot of people feel very different about this. There are also people who dislike optional content very much. I guess they don't want to miss anything, but there's no way around it. Currently it's already not possible to see all available content in one playthrough.
