With some help from @LydianChord I was finally able to fix a nasty bug that would occasionally cause the game to crash. It turns out the bug would occur if the AI had to evaluate a position where a king was in the upper left corner of the board. Understandably, it was a pretty rare bug  so I'm quite relieved I was finally able to track it down.



With this specific bug fixed I'm also publishing the game more widely. I've uploaded it to Kongregate and Newgrounds. If you like it, you could help me out by giving the game an upvote on those platforms!
