I also used the line-of-sight code to generate an intelligent gunsight which can identify whether or not you can hit whatever you are aiming at from your current location. There's also animated water tiles now, which are kind of pleasant to look at but won't win any awards (mostly because they are only a few frames of NES-style hilarity).
Blood is a little bit faster to deal with, I wrote some optimizations when I was in there fitting my new assert function (which uses the __FILE__ and __LINE__ macros for even better debugging hilarity!).
I will proceed to make more advancements in game quality and report back when I have an AI character running about, freaking out when you shoot your gun at them, and eventually dying in a pool of their own blood like a dog.
I said 'hilarity' a lot in this entry. I think I need some more pie.
