I love this. I aspire to, someday, create a roguelike and love seeing this kind of code - even though I can't tell what it does! That's my only complaint actually - I wish there were a lot of comments explaining everything. Granted, it's an engine, not a tutorial - I think it is great for what it was - I'd like to see a lot more of this kind of thing! It takes a surprisingly long time to load on my system (which is somewhat top of the line) but I imagine it is doing quite a bit of number crunching - or whatever it is doing- and maybe with more development it could be faster. 4 stars, going to play with it and see if I can make any use of it and maybe come back and give it 5 stars if so!
