Apologies for the short, shallow review but I did want to mention a couple things and I just didn't find myself interested enough to keep playing.
First, your movement is broken. I remember a review that said this earlier, but I wanted to tell you exactly why it's broken and how to fix it. The review said you snap back into place after pressing the key for a short period of time, and you responded saying it's a design choice because some colleagues of yours found out they sometimes moved accidentally. The problem isn't that they moved accidentally, then problem is when they moved accidentally it was more of a pain to get back to where they were before. That indicates the movement is simply too slow, which is an easy fix.
When you see a problem or when someone tells you there's a problem, don't fix that directly because usually that means there's a deeper underlying cause and your fix won't do anything except waste your time.
Next, I don't believe this has any replay value. You play it once, find the king, and then you close out and never come back to it again. I would suggest randomizing the king's position or the map some to give it replay value. Then add a high-score table so the player is aware there's replay value and can challenge their friends.
Finally, the graphic style is interesting but lacks color or definition. I understand the art style you were going for, and i'm being a bit nitpicky now, but for me it would have been nice if the graphics had something else with them.
A thought-out game meets an okay mechanic and is implemented "meh"-ly - all-in-all not bad but not something i'd spend a lot of my time on.
