As I understand it, the way Greenlight works is that new entrants get added to everyone's review queues, which means that at the start of the process, votes accumulate with deceptive speed. Right now, less than a day after submission, the game's accumulated 17% of the votes to get to that magic top 100 likely to gain entry into Steam in the next round.
At some point, this easy accumulation of votes will cease, and the real slog of getting greenlit will begin. This means I very much rely on your upvotes. Please check it out and vote on it, even if you already have a copy. When it's gone through, I will see that I can give Steam keys to existing purchases.
Development will of course continue no matter how the greenlighting goes, but I'm understandably very keen to have as wide a set of distribution channels as possible, and making the game available on Steam is a big part of that.
