Don't have it done yet, but had enough time to lay the foundation for it.
I thought about adding some extra special game modes too. Zombie mode - you want to hunt for the brains within a certain number of moves. Hell mode - the numbers have been replaced with demonic glyphs with the catch that a certain glyph's associated number is randomized every time!
Hopefully will have enough time tomorrow to polish it up and finish it so it's fully playable.
