This game is already finished. But I guess that you're asking about a sequel called Knightin'+. It's almost done. Final dungeon is almost finished. I'm going to release it right after the winter holidays. You may expect new update for Knightin' and demo of Knightin'+ soon.
This is just a small game made for a contest. I didn't plan to expand it at first. But lots of people all over the internet convinced me to change my mind. Knightin'+ is a sequel that will have a separate demo version. Why don't I want to use this game as a demo? I liked my idea with QR codes containing solutions. But unfortunately most of the gamers disliked it very much. So I removed them in sequel and redesigned the first dungeon. I want this particular game to remain in its original form as a contest entry with QR codes :)
