Yeah, I saw your older systems in the links you gave me, so I knew you had implemented it before. If not I would probably be quite disheartened by how fast you got this far, seeing how long it took me 
It seems like we are doing similar things when it comes to tile costs, with both of us doing things similar to, but not exactly like Dijkstra.
Your debugging tools look really neat. I haven’t got anything like that myself. I guess you saw the benefit of them immediately, as you have more of a programming background than me. It will probably be very useful for users. I also see the differences between our systems to be you providing more of a bare-bones framework, which is perfect if you need the basics in place to build your own system without any clutter. My system will be better if you want a more complete system out of the box, that you can tweak and customize.
You’ve done AI before, right? It seemed like it in the video link you gave me. I’m planning on making actual artificial intelligence, that weighs the costs and benefits of all possible paths and choosing the most beneficial. Later I plan to add the ability to tweak the personality of different AIs to make some more agressive, for instance, and perhaps throw in some random elements.
