As the game is published in almost finished version, it might recieve updates or continuation but most likely not. It's more likely that it is going to be released with no updates afterwards in a month or two. As I am not a big fan of adding small amount of content each month.
For me leaving the project is not the same thing as releasing with enough content in it. So, it's going to be released soon and if we would have good enough results, we're going to make similar games to this.
Thanks for noticing that we actually tried to make gameplay & story worth spending time on. Hope the answer helped you.
