I did some googling and can't even find any information as to whether or not they're even still working on this, or if it has just been silently discarded. ;o/
I wish the developers would just give us an update and tell us anything at all. Don't even need a release date, just "yes, it's still being worked on and it definitely is going to happen" would be nice. It is 10 months now since it was released on Steam and I'm not feeling like I'm considered an equal customer just because I bought it here now.
Maybe they decided to cancel it and just don't want to say anything fearing people being upset about it, who knows. I'd rather know than be left hanging in the dark though. A concrete decision and good communication beats leaving things up in the air and people in the dark in terms of customer trust IMHO. I'm still looking forward to it but losing my enthusiasm as each month passes.
