I have estimated that I will not be able to finish this challenge in time. I have started it too late and without a clear direction from the beginning.
I managed to finish the necromancer character, the AI and most of the map. But I had some problems with projectiles going through walls and sometimes going in weird directions without any kind of apparent reason why.
I have decided not to release the game as it is because it has some broken gameplay mechanics and I'd rather not release the game like this. I might continue working on it when I have more time and not be busy with other things as well.
Well, it was fun anyway and congrats to the community members who succeeded in this challenge!
